Global Technology's capital structure is as follows:

The aftertax cost of debt is $6\mathrm{.}50$ percent; the cost of preferred stock is

$10\mathrm{.}50$ percent; and the cost of common equity $($in the form of retained

earnings$)$ is $13\mathrm{.}50$ percent.

Calculate the Global Technology's 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: $(k_d)(w_d)=$ weighted cost of debt.
