Answer:
WACC for A: 9.05%
WACC for B: 9.50%
WACC for C: 12.20%
WACC for D: 12.65%
Explanation:
WACC for a division will be equal: Percentage of Debt in capital employed by the Division x Cost of Debt + Percentage of Equity in capital employed by the Division x Cost of equity = 50% x 6% + 50% x ( Risk free rate + Beta of each Division x Risk premium) = 3% + 50% x ( 4% + beta of each Division x Risk premium)
Risk premium for the 4 Divisions is equal to (Cost of equity for the whole firm - Risk free rate) / beta = 9%
Thus WACC for a division will be equal: 3% + 50% x ( 4% + beta of each Division x 9%).
Substitute beta of each Division from A to D provided in the question, we have: WACC for A: 9.05%; WACC for B: 9.5%; WACC for C: 12.2%; WACC for D: 12.65%.
Answer: The minimum number of students you need if you want the margin of error to be 5% IS 278.
Explanation:
Cochran’s Sample Size Formula gives the minimum number of students as 
Where:
e is the desired level of precision (i.e. the margin of error),
p is the (estimated) proportion of the population which has the attribute in question and q is 1 – p.
The z-value for 95% confidence interval is found to be 1.96 in a Z table.
Assuming that half of the teenagers favor the elimination of a curfew: this gives us maximum variability. So p = 0.5 and q=0.5.
Then 
Rounding up, 
But considering that 1000 is a small population, we can modify the sample size we calculated above formula by using this equation:
Where s is the adjusted sample size, n is the original sample size we calculated and N is the population size.
Answer:
To calculate the after-tax cost of debt, multiply the before-tax cost of debt by <u>(1 - tax rate)</u>.
Water and Power Company (WPC) can borrow funds at an interest rate of 10.20% for a period of four years. Its marginal federal-plus-state tax rate is 45%. WPC's after-tax cost of debt is <u>= 10.20% x (1 - 45%) = 5.61%</u>.
At the present time, Water and Power Company (WPC) has 15-year noncallable bonds with a face value of $1,000 that are outstanding. These bonds have a current market price of $1,329.55 per bond, carry a coupon rate of 12%, and distribute annual coupon payments. The company incurs a federal-plus-state tax rate of 45%. If WPC wants to issue new debt, what would be a reasonable estimate for its after-tax cost of debt (rounded to two decimal places)?
<u>B. 4.47%</u>
pre-tax cost of debt = bond's yield to maturity
approximate YTM = {120 + [(1,000 - 1,329.55)/15] / [(1,000 + 1,329.55)/2] = 98.03 / 1,164.775 = 0.08416 = 8.416%
approximate after tax cost of debt = 8.4% x (1 - 45%) = 4.62 = 4.62
since I used the approximate yield to maturity, my answer is not exact. That is why I have to look for the closest available option.
Answer:
The question is not complete,find below complete questions:
If you purchased a $50 face value bond in early 2017 at the then current interest rate of .10 percent per year, how much would the bond be worth in 2027? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) c. In 2027, instead of cashing the bond in for its then current value, you decide to hold the bond until it doubles in face value in 2037. What annual rate of return will you earn over the last 10 years?
The bond is worth $50.50 in the year 2027
The annual rate of return is 7.07%
Explanation:
The future value of the bond is given by the below formula:
FV=PV*(1+r)^N
where PV is the present of the bond of $50
r is the rate of return of 0.10 percent=0.001
N is the duration of the bond investment of 10 years
FV=50*(1+0.001
)^10
FV=$50.50
However for the face of the bond to double i.e to $100, the rate of return can be computed thus:
r=(FV/PV)^(1/N)-1
where FV=$100 (double of $50)
FV=$50.50(current value in 2027)
N=10
r=($100/$50.50)^(1/10)-1
r=0.070707543
r=7.07%
