Global Technologys capital structure is as follows:

Debt	15	%
Preferred stock	50
Common equity	35

The aftertax cost of debt is 8.50 percent; the cost of preferred stock is 12.00 percent; and the cost of common equity (in the form of retained earnings) is 15.50 percent.

Calculate the Global Technologys weighted cost of each source of capital and the weighted average cost of capital. (Do not round intermediate calculations. Input your answers as a percent rounded to 2 decimal places.) Notice that this problem asks for the weighted costs. These are the unweighted costs times the weights. Like this: (kd)(wd) = weighted cost of debt.
