Investors require an after-tax rate of return of 10% on their stock investments. Assume that the tax rate on dividends is 30% while capital gains escape taxation. A firm will pay a $4 per share dividend 1 year from now, after which the firm's stock is expected to sell at a price of $45.

a. Find the current price of the stock. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

b. Find the expected before-tax rate of return for a 1-year holding period. (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.)

c. Now suppose that the dividend will be $7 per share. If the expected after-tax rate of return is still 10% and investors still expect the stock to sell at $45 in 1 year, at what price must the stock now sell? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

d. What is the before-tax rate of return? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.)
