Question 4 1 pts (Ref. Unit 10 Exercise 5) You are estimating the weighted average cost of capital (WACC) for a company. The company has a debt-to-equity ratio, D/E of 1.0, which means that the company has the same amount of debt and equity values (D/E = 1 D = E). The required rate of return on the company's stock is 15%. The yield to maturity of the company's outstanding bonds is 6%. The company is subject to a 21% income tax rate. What is the company's WACC in percentage (%)? Hint: You can assume any value for the equity (or debt, but not both). For example, you can set the equity value E = 1. Note: Write your answer in % terms (do not round). For example, write 2.54 (%) instead of 0.0254. D
