Now it's time for you to practice what you've learned. Suppose Mullens Corporation is considering three average-risk projects with the following costs and rates of return: Mullens estimates that it can issue debt at a rate of rd=30.00% and a tax rate of T=30.00%. It can issue preferred stock that pays a constant dividend of Dp=$5.00 per year and at Pp=$10.00 per share. Also, its common stock currently sells for P0=$7.50 per share. The expected dividend payment of the common stock is D1=$3.00 and the dividend is expected to grow at a constant annual rate of g=10.00% per year. Mullens' target capital structure consists of ws=65.00% common stock, wd=25.00% debt, and wp=10.00% preferred stock. The after-tax cost of debt is approximately The cost of preferred stock is approximately The cost of common stock is approximately The WAAC is approximately
