A firm has zero debt in its capital structure. Its overall cost of capital is 10 percent. The firm is considering a new capital structure with 60 percent debt. The interest rate on the debt would be 8 percent. Assuming there are no taxes, its cost of equity capital with the new capital structure would be
13%
A firm's return on assets is 12 percent and the cost of the firm's debt is 7 percent. Given a 0.7 debt-equity-ratio, what is the levered cost of equity? Assume that there are no taxes.
15.5%
Stock A has an expected return of 10 percent per year and stock B has an expected return of 20 percent. If 40 percent of a portfolio's funds are invested in stock A and the rest in stock B, what is the expected return on the portfolio of stock A and stock B?
16%
The M&M Company is financed by $10 million in debt (market value) and $40 million in equity (market value). The cost of debt is 10 percent and the cost of equity is 20 percent. Calculate the weighted average cost of capital, assuming no taxes.
18%
Suppose the beta of Amazon is 2.2, the risk-free rate is 5.5 percent, and the market risk premium is 8 percent. Calculate the expected rate of return for Amazon.
23.1%

7.7%
Given are the following data: Cost of debt = rD = 6%; Cost of equity = rE = 12.1%; Marginal tax rate = 35%; and the firm has 50 percent debt and 50 percent equity. Calculate the after-tax weighted average cost of capital (WACC).
8%
The M&M Company is financed by $4 million (market value) in debt and $6 million (market value) in equity. The cost of debt is 5 percent and the cost of equity is 10 percent. Calculate the weighted average cost of capital. (Assume no taxes.)

Assume the following data for a stock: Beta = 0.9; risk-free rate = 4 percent; market rate of return = 14 percent; and expected rate of return on the stock = 13 percent. Then the stock is
correctly priced
Assume the following data for a stock: Beta = 1.5; risk-free rate = 4 percent; market rate of return = 12 percent; and expected rate of return on the stock = 15 percent. Then the stock is
overpriced
Assume the following data for a stock: Beta = 0.5; risk-free rate = 4 percent; market rate of return = 12 percent; and expected rate of return on the stock = 10 percent. Then the stock is
underpriced
