Mary Willis is the advertising manager for Bargain Shoe Store. She is currently working on a major promotional campaign. Her ideas include the installation of a new lighting system and increased display space that will add $24,000 in fixed costs to the $270,000 currently spent. In addition, Mary is proposing that a 5% price decrease ($40 to $38) will produce a 20% increase in sales volume (20,000 to 24,000). Variable costs will remain at $24 per pair of shoes. Management is impressed with Mary's ideas but concerned about the effects that these changes will have on the break-even point and the margin of safety. Compute break-even point and margin of safety ratio, and prepare a CVP income statement before and after changes in business environment.

Answers

Answer 1

Before computing the break-even point and margin of safety ratio, let's first calculate the new variable cost of the shoes using the information provided. Variable cost per pair of shoes = $24Fixed cost = $270,000 + $24,000 = $294,000New selling price per pair of shoes = $38The contribution margin per pair of shoes can now be computed as follows:

Contribution margin = Selling price per pair of shoes - Variable cost per pair of shoes Contribution margin = $38 - $24Contribution margin = $14Now, let's compute the break-even point:

BEP = Fixed cost / Contribution marginBEP = $294,000 / $14BEP ≈ 21,000 pairs of shoes Next, let's compute the margin of safety ratio:Margin of safety ratio = (Current sales - BEP) / Current sales margin of safety ratio = (20,000 - 21,000) / 20,000Margin of safety ratio = -0.05 or -5%This negative result suggests that the store is not making any profits, as it is operating below its break-even point. Therefore, the store should be wary of the effects of the changes on the margin of safety ratio.

Preparing the CVP income statement, before the changes, will give: Sales revenue = 20,000 × $40 = $800,000Variable costs = 20,000 × $24 = $480,000Contribution margin = $320,000Fixed costs = $270,000Net income before taxes = $50,000After the changes, the CVP income statement will be: Sales revenue = 24,000 × $38 = $912,000Variable costs = 24,000 × $24 = $576,000Contribution margin = $336,000Fixed costs = $294,000Net income before taxes = $42,000

Assume you have a 1-year investment horizon and are trying to choose among three bonds. All have the same degree of default risk and mature in 10 years. The first is a zero-coupon bond that pays $1,00

Answers

Ai. The price of a zero-coupon bond is $463.19, ii. The price of the bond is $1,134.20, iii. 10% coupon bond is $1,000.00.

Bi. The price of the zero-coupon bond will remain the same at $1,000.00, ii. 8% coupon bond is $500.25, iii. The price remains the same at $1,000.00

What are the responses to other questions?

a. If all three bonds are priced to yield 8% to maturity, the prices of the bonds are as follows:

(i) Zero-coupon bond: The formula to calculate the price of a zero-coupon bond is given by P = F / (1 + r)ⁿ, where P is the price, F is the face value, r is the yield rate, and n is the number of years to maturity.

In this case, the face value is $1,000, the yield rate is 8% (0.08), and the number of years to maturity is 10. Plugging in these values, we get:

P = 1000 / (1 + 0.08)¹⁰ = $463.19

(ii) 8% coupon bond: The price of the bond can be calculated by discounting the annual coupon payments and the face value using the yield rate.

The annual coupon payment is $80, the yield rate is 8% (0.08), and the number of years to maturity is 10. Since the coupon payment is an annuity, we can use the present value of an annuity formula to calculate the price.

P = (C / r) × (1 - 1 / (1 + r)ⁿ) + F / (1 + r)ⁿ

= (80 / 0.08) × (1 - 1 / (1 + 0.08)¹⁰) + 1000 / (1 + 0.08)¹⁰

= $909.09 + $225.11

= $1,134.20

(iii) 10% coupon bond: Using the same approach as the 8% coupon bond:

P = (C / r) × (1 - 1 / (1 + r)ⁿ) + F / (1 + r)ⁿ

= (100 / 0.08) × (1 - 1 / (1 + 0.08)¹⁰) + 1000 / (1 + 0.08)¹⁰

= $1,000.00

b. If you expect the yields to maturity to be 8% at the beginning of next year, the prices of the bonds will be:

(i) Zero-coupon bond: The price of the zero-coupon bond will remain the same at $1,000.00 since there are no coupon payments.

(ii) 8% coupon bond: The price can be calculated using the same approach as in part (a)(ii) but with a yield rate of 8% for the next year.

P = (80 / 0.08) × (1 - 1 / (1 + 0.08)⁹) + 1000 / (1 + 0.08)⁹

= $500.25

(iii) 10% coupon bond: The price remains the same at $1,000.00 since the coupon rate and yield rate are the same.

c. The before-tax holding-period return on each bond is equal to the yield rate, which is 8% for all three bonds.

d. If your tax bracket is 30% on ordinary income and 20% on capital gains income, the after-tax rate of return on each bond can be calculated as follows:

(i) Zero-coupon bond:

Pre-tax rate of return: 8%

After-tax rate of return: 8% (no tax on capital gains)

(ii) 8% coupon bond:

Pre-tax rate of return: 8%

After-tax rate of return: 8% - (8% × 30%) = 5.60%

(iii) 10% coupon

bond:

Pre-tax rate of return: 8%

After-tax rate of return: 8% - (8% × 30%) = 5.60%

e. If you expect the yields to maturity on each bond to be 7% at the beginning of next year, the calculations for parts (b)-(d) will change accordingly:

(b) The prices of the bonds will be as follows:

(i) Zero-coupon bond: $1,000.00 (no change)

(ii) 8% coupon bond: $454.55

(iii) 10% coupon bond: $1,000.00 (no change)

(d) The after-tax rate of return on each bond will be as follows:

(i) Zero-coupon bond: 7% (no tax on capital gains)

(ii) 8% coupon bond: 7% - (7% × 30%) = 4.90%

(iii) 10% coupon bond: 7% - (7% × 30%) = 4.90%

Today, the exchange rate between the US dollar and Appleland's currency is $1.000=AAA8.67, and between the US dollar and Bananaland's currency is $0.401=BBB1.000.

Calculate the implied cross-rate between Appleland's and Bananaland's currencies, expressed as the amount of BBB per one unit of AAA.

Answers

The implied cross-rate between Appleland's and Bananaland's currencies, expressed as the amount of BBB per one unit of AAA, is approximately 3.476767 BBB per one unit of AAA.

To calculate the implied cross-rate between Appleland's and Bananaland's currencies, we can use the exchange rates provided for each currency against the US dollar.

Given that $1.000 is equivalent to AAA8.67 in Appleland's currency and $0.401 is equivalent to BBB1.000 in Bananaland's currency, we can set up a proportion to find the cross-rate:

AAA8.67 / $1.000 = BBB1.000 / $0.401

To simplify the calculation, we can convert the exchange rates to a common currency. Let's convert both rates to US dollars:

AAA1 = $1.000 / AAA8.67

BBB1 = $0.401 / BBB1.000

Now we have:

AAA1 / $1.000 = BBB1 / $0.401

To find the implied cross-rate between Appleland's and Bananaland's currencies, we need to solve for BBB1 / AAA1:

BBB1 / AAA1 = ($0.401 / BBB1.000) / ($1.000 / AAA8.67)

Simplifying the expression, we get:

BBB1 / AAA1 = (0.401 * AAA8.67) / BBB1.000

Calculating the right side of the equation, we have:

BBB1 / AAA1 = 3.476767 / BBB1

Answers

The receivables period is approximately 45 days and the annual credit sales are $175,000.

The average number of days it takes for a company to collect payment after a sale has been made is known as the receivables period, which is also known as the day's sales outstanding (DSO). The formula to determine the Receivables period is given as,

Receivables period = (Accounts receivable / Annual credit sales) × 365

Given data:

Annual credit sales = $175,000.

accounts receivable = 21,000 and 22,000

The average accounts receivable for the period = ($21,000 + $22,000) / 2

= $21,500.

Substuting the values into the formula gives us:

Receivables period = ($21,500 / $175,000) × 365

Q1. A firm's total cost function is c(y) = y² + (a + B)y + 100ß. p = $50. Find the best output level, y*.

Answers

The required solution is `(a + B - 50)/2`.

The firm's total cost function is, `c(y) = y² + (a + B)y + 100ß`.The price is, `p = $50`.To find: The best output level, `y*`.

Formula used: Total Revenue = Price × Quantity Total Cost = Fixed Cost + Variable Cost Total Profit = Total Revenue - Total Cost. To find the best output level, we need to find out the profit and then derive the total profit equation by differentiating the profit equation with respect to the output level and equate it to zero.

Here, the total cost function can be represented as follows: c(y) = y² + (a + B)y + 100ß Using the formula, Total Revenue = Price × Quantity or, R(y) = p × y= $50 × y= 50yUsing the above cost and revenue equation, Total Profit = Total Revenue - Total Cost or, P(y) = R(y) - C(y)or, P(y) = 50y - (y² + (a + B)y + 100ß)or, P(y) = - y² - (a + B - 50)y - 100ß

Differentiate the profit function with respect to output level to get the maximum profit .p'(y) = - 2y - (a + B - 50)Setting `p'(y) = 0`, we get- 2y - (a + B - 50) = 0or, 2y = - (a + B - 50)or, y = `(a + B - 50)/2`.

When the yield to maturity of a bond exceeds its coupon rate, the bond sells at a discount from par, whereas when the yield to maturity is less than its coupon rate, the bond sells at a premium from par. In general, when the yield to maturity is less than the coupon rate, the bond will sell for more than its par value, while when the yield to maturity exceeds the coupon rate, the bond will sell for less than its par value.  

The equation for the present value of a bond is as follows:

b. If Lourdes plans to raise additional capital and wants to use debt financing, what coupon rate would it have to set in order to issue new bonds at par?

Answers

a) For estimating the remaining life of the bonds we need to determine the bond's yield to maturity (YTM).

Which can be calculated using a financial calculator, which is provided as follows:PV = -1,331.28FV = 1,000PMT = 13/2 * 1,000 = $65n = 30*2 = 60i =?Here, we need to calculate the semiannual yield, which should be adjusted for semiannual payments. To estimate the bond's remaining life, we need to find the number of periods remaining, which can be calculated by subtracting the number of years passed from the total number of years until maturity. The best estimate of these bonds' remaining life is 54 years (60 - 6 years).

b) The coupon rate at which the bond will be issued can be calculated using the following formula:

Par value = Coupon payment * (1 - 1 / (1 + r)n) / r + FV / (1 + r)n where, r = Coupon rate PMT = 1,000FV = 1,000n = 30 * 2 = 60PV = Par value = $1,000We need to solve for r to find the coupon rate.

Substituting the values in the formula, we get:$1,000 = Coupon payment * (1 - 1 / (1 + r)60) / r + $1,000 / (1 + r)60

Simplifying the equation, we get: Coupon payment = $50.70

Therefore, the coupon rate at which the bond will be issued at par value is 5.07%

The percentage increase in sales is 25%.EBIT2 = EBIT1 * (Sales1 + 0.25 * Sales1) / Sales1EBIT2 = $105,000 * (1 + 0.25) / 1EBIT2 = $131,250 Therefore, the EBIT for this firm if sales do not increase is $131,250.

Given, the degree of financial leverage (DFL) = 1.10Percentage increase in sales = 25%Percentage increase in EPS = 50%EBIT = $105,000Let's first calculate the EBIT at 50% increase in EPS by using the formula of DFLDegree of Financial Leverage (DFL) = Percentage change in EPS / Percentage change in EBIT1.10 = 50% / Percentage change in EBITPercentage change in EBIT = 50% / 1.10Percentage change in EBIT = 45.45%EBIT at 50% increase in EPS = $105,000 / 1.4545EBIT at 50% increase in EPS = $72,260.16To find the EBIT when sales do not increase, we can use the following formula; EBIT = Sales - Variable Costs - Fixed CostsNow we can assume the variable costs and fixed costs to be constant.

Hence, EBIT is directly proportional to sales and we can use the following formula to find the EBIT when sales do not increase. EBIT1 / EBIT2 = Sales1 / Sales2Let EBIT2 be the EBIT when sales do not increase and Sales1 be the original sales. So, we can write; EBIT1 / EBIT2 = Sales1 / (Sales1 + 0.25 * Sales1)Since the percentage increase in sales is 25%.EBIT2 = EBIT1 * (Sales1 + 0.25 * Sales1) / Sales1EBIT2 = $105,000 * (1 + 0.25) / 1EBIT2 = $131,250Therefore, the EBIT for this firm if sales do not increase is $131,250.

V (In the unlikely case that your computer cannot read the expression above properly, here it is again: q = f(K,L) = {sqrt(K)+sqrt (L)}/18. Note that the corresponding isoquants have typical, downward-sloping, convex shape. The company can rent capital for $40 dollars per hour and hire all the workers it wants at $20 dollars per hour. a) [5 points] What are the cost minimising capital and labour inputs for MedM, Inc. in order to produce q units of output? Illustrate on a graph with an isoquant and isocosts. Put labour on a horizontal axis. b) [2 points] Derive an expression for the output expansion path and draw the path on a graph with isoquants and isocosts. c) [3 points] Given you answer to a), find the long run cost function CLR(q). Calculate the corresponding marginal cost function MCLR(q). Sketch cost and marginal cost functions on separate graphs.

Answers

The production function is given as q = f(K, L) = {sqrt(K)+sqrt (L)}/18. MedM, Inc. is using capital and labour to produce high-quality medical equipment. The cost of capital per hour is $40.The cost of labour per hour is $20.Therefore, the total cost (TC) equation is given as: TC = wL + rKK = Capital and L = Labour. MedM, Inc. has to minimize its costs to produce q units of output.

To minimize costs, the company can use the equation: Marginal rate of technical substitution (MRTS) = (-MP_L) / MP_K. Also, MRTS = (w/r)Therefore, (-MP_L) / MP_K = (w/r)(-MP_L) / (1/2sqrt(L)) = (20/40)MP_K / (1/2sqrt(K)) = (1/2sqrt(L)/2sqrt(K))K/L = 1. The cost-minimizing labor and capital are given by: K* = q^2/16L* = q^2/16. The isoquant is drawn below: The budget equation is given as wL + rK = C. Substituting K* and L* into the budget equation: wL* + rK* = C(20)(q^2/16) + (40)(q^2/16) = C5q^2 = C. The iso cost line is drawn below

(b) The output expansion path is the curve that represents the cost-minimizing combination of labour and capital for different levels of output. It is obtained by taking the cost-minimizing combination of capital and labour for different levels of output. The output expansion path is given by: K* = (1/2)(q^2)/L*L* = (1/2)(q^2)/K. The output expansion path is shown below: The isoquants and iso cost line are also shown.

(c) The long-run cost function is the lowest cost at which the firm can produce a given level of output, q. The long-run cost function, CLR(q), is given by: CLR(q) = min {wL + rK}. Subject to the constraint: f(K, L) = q .Substituting the production function, f(K, L), into the cost function, we get: CLR(q) = wL* + rK*CLR(q) = (20)(q^2/16) + (40)(q^2/16)CLR(q) = 3q^2. The marginal cost function is the rate of change of the long-run cost function with respect to output, q. Marginal cost function, MCLR(q), is given by: MCLR(q) = d(CLR(q))/dq MCLR(q) = d(3q^2)/dq MCLR(q) = 6q.

The higher taxation of labour income with respect to capital gains: Increases inequality because reduces labour supply Decreases inequality because it increases the returns for small investors Increases inequality because it increases r-g Decreases inequality because it decreases r-g

Answers

The higher taxation of labor income with respect to capital gains: Increases inequality because it increases r-g.R-g refers to the rate of return on capital (r) relative to the rate of economic growth (g).The more significant the difference between r and g, the more unequal a society becomes. Capital owners earn more returns, and the wealth gap between the rich and poor widens.

When labor income is taxed at a higher rate than capital gains, the tax code reinforces this inequality. Therefore, the statement that is true about higher taxation of labor income with respect to capital gains is that it increases inequality because it increases r-g.Hence, option C is the correct answer.

A country which does not tax cigarettes is considering the introduction of a $0.80 per pack tax. The economic advisors to the country estimate the supply and demand curves for cigarettes as: QD = 180 - 15P QS = 20 + 65P where Q = daily sales in thousands packs of cigarettes, and P = price per pack. The country has hired you to provide the following information regarding the cigarette market and the proposed tax. Show you work to get credit. What are the equilibrium values in the current environment with no tax? What price and quantity would prevail after the imposition of the tax? What portion of the tax would be borne by buyers and sellers respectively? Calculate the deadweight loss from the tax. Could the tax be justified despite the deadweight loss? What tax revenue will be generated?

Answers

To find the equilibrium values in the current environment with no tax, we need to set the quantity demanded equal to the quantity supplied. The demand equation is QD = 180 - 15P, and the supply equation is QS = 20 + 65P. By setting these two equations equal to each other, we can solve for the equilibrium price and quantity.

180 - 15P = 20 + 65P

Simplifying the equation, we get:

180 - 20 = 65P + 15P

160 = 80P

P = 2

Substituting the equilibrium price (P = 2) back into either the demand or supply equation, we can find the equilibrium quantity:

QD = 180 - 15(2) = 180 - 30 = 150

Therefore, in the current environment with no tax, the equilibrium price is $2 per pack and the equilibrium quantity is 150,000 packs of cigarettes.

After the imposition of the $0.80 per pack tax, the price paid by buyers will increase by the full amount of the tax, while the price received by sellers will decrease by the same amount. The new price paid by buyers will be $2 + $0.80 = $2.80 per pack, and the price received by sellers will be $2.80 - $0.80 = $2.00 per pack.

To find the new quantity demanded and supplied, we substitute the new price into the demand and supply equations:

QD = 180 - 15(2.80) = 180 - 42 = 138

QS = 20 + 65(2) = 20 + 130 = 150

Therefore, after the imposition of the tax, the new equilibrium price will be $2.80 per pack, and the new equilibrium quantity will be 138,000 packs of cigarettes.

The portion of the tax borne by buyers is the difference between the original price ($2) and the price paid by buyers after the tax ($2.80), which is $0.80. The portion of the tax borne by sellers is the difference between the price received by sellers before the tax ($2) and the new price received after the tax ($2.00), which is $0.80 as well.

To calculate the deadweight loss from the tax, we need to compare the original equilibrium quantity (150,000 packs) with the new equilibrium quantity after the tax (138,000 packs). The deadweight loss represents the loss in total surplus due to the inefficiency created by the tax.

Deadweight Loss = 0.5 * (150,000 - 138,000) * ($2.80 - $2)

Deadweight Loss = 0.5 * 12,000 * $0.80

Deadweight Loss = $4,800

The tax revenue generated can be calculated by multiplying the tax per pack ($0.80) by the new equilibrium quantity (138,000 packs):

Tax Revenue = $0.80 * 138,000 = $110,400

Despite the deadweight loss, the tax could be justified if the government aims to achieve other objectives, such as reducing cigarette consumption for public health reasons or generating revenue for public programs. However, the deadweight loss indicates that the tax creates an inefficiency in the market by reducing overall welfare.

T/F: The ratio of aggregate consumption expenditure to aggregate income is known, as Marginal propensity to consume

Answers

The given statement is False. Marginal propensity to consume is not the ratio of aggregate consumption expenditure to aggregate income. Instead, it is defined as the proportion of a change in income that is spent on consumption.

Marginal propensity to consume (MPC) is the slope of the consumption function and it measures the change in consumer spending resulting from a change in disposable income. A higher MPC indicates a greater likelihood of consumers to spend an increase in their income on goods and services, whereas a lower MPC suggests that consumers are more inclined to save the extra income.

The formula for calculating MPC is as follows:MPC = change in consumption / change in incomeAggregate consumption expenditure (C) is the total amount spent on consumption goods and services by individuals and the government in an economy, while aggregate income (Y) is the total income earned by households, businesses, and the government in an economy.

The ratio of aggregate consumption expenditure to aggregate income is known as the average propensity to consume (APC), which is a different concept from MPC. AP is the proportion of total income that is spent on consumption, while MPC is the proportion of a change in income that is spent on consumption.

The formula for calculating APC is:APC = consumption / incomeTherefore, the given statement is False as MPC is not the ratio of aggregate consumption expenditure to aggregate income.

What is the addition to retained earnings? (Do not round intermediate calculations.) Addition to retained earnings

Answers

The addition to retained earnings for Nataro, Incorporated is $119,200

To calculate the addition to retained earnings, we need to start with the net income, subtract dividends, and account for taxes.

Net income can be calculated as follows:

Net Income = Sales - Costs - Depreciation Expense - Interest Expense

Net Income = $666,000 - $328,000 - $72,000 - $46,000

Net Income = $220,000

Next, we need to calculate the tax expense:

Tax Expense = Net Income * Tax Rate

Tax Expense = $220,000 * 0.24

Tax Expense = $52,800

Now we can calculate the addition to retained earnings:

Addition to Retained Earnings = Net Income - Tax Expense - Dividends

Addition to Retained Earnings = $220,000 - $52,800 - $48,000

Addition to Retained Earnings = $119,200

How is net income represented on the worksheet in terms of columns?

Net income is represented on the worksheet in the income statement debit column and balance sheet credit column. Net income, also known as the bottom line or profit, is a key financial metric that reflects a company's earnings after deducting all expenses from its total revenue. On a worksheet, which is a financial document used for preparing financial statements, net income is typically recorded in two columns: the income statement debit column and the balance sheet credit column.

The income statement debit column is where all the expenses, such as salaries, rent, and utilities, are recorded as debits. Net income is calculated by subtracting the total expenses from the total revenue, and the resulting amount is entered as a credit in the income statement debit column. On the other hand, the balance sheet credit column is used to record the net income as a credit entry. This reflects the fact that net income increases the equity or retained earnings of the company, which is a credit account on the balance sheet.

What does a convex tax code imply? How does a company benefit
from hedging if it faces a convex tax code? If the corporate tax
rate is flat, would a firm benefit from hedging?

Answers

A convex tax code means that the effective tax rate increases as taxable income increases at an increasing rate. When the tax code is convex, a firm will benefit from hedging.

Let's discuss how a company benefits from hedging if it faces a convex tax code and if the corporate tax rate is flat. If a company faces a convex tax code, then it implies that the effective tax rate rises faster than the nominal tax rate. A company can benefit from hedging in such a situation because if it generates positive cash flows, then the incremental tax paid on the additional cash flows will be higher than the average tax paid on the existing cash flows. The company can reduce its tax payments by decreasing its future taxable income through hedging.

Therefore, a company can benefit from hedging when it faces a convex tax code. However, if the corporate tax rate is flat, then a firm would not benefit from hedging because a firm's tax liability would not change due to hedging. Therefore, a firm would not benefit from hedging when the corporate tax rate is flat. In conclusion, a convex tax code implies that the effective tax rate increases as taxable income increases at an increasing rate. A company benefits from hedging when it faces a convex tax code but would not benefit from hedging when the corporate tax rate is flat.

Answers

In this scenario, the residents of the city have a willingness to pay for apple juice, ranging from $10 for the first bottle to $2 for the fifth bottle and beyond. The cost of producing a bottle of apple juice is $5, and each bottle has an external cost of $2 due to pollution.

Considering these factors, the market for apple juice operates as a competitive market, where suppliers sell the juice at a price of $5 and residents purchase it based on their willingness to pay.

In a competitive market, the equilibrium price and quantity are determined by the intersection of the demand and supply curves. The willingness to pay by the residents represents the demand curve, while the cost of production and the external cost represent the supply curve.

Since the suppliers are selling apple juice at the cost of production ($5), the market price is determined by the maximum willingness to pay among the residents, which is $10. At this price, the first bottle will be sold to those willing to pay $10, and the quantity demanded will be equal to the quantity supplied.

However, due to the external cost of $2 per bottle, the true cost of production is $7. This means that the market price of $10 does not fully account for the external cost. From an economic perspective, this creates a market failure, as the price does not reflect the full social cost of production.

To address this market failure and account for the external cost, policymakers may consider implementing measures such as taxes or regulations to internalize the external cost and achieve a socially optimal outcome.
