Global Technology's capital structure is as follows:

$\backslash$table$[[$Debt$,508],[$Preferred stock,$35],[$Common equity,$15]]$

The aftertax cost of debt is $8\mathrm{.}50$ percent; the cost of preferred stock is $12\mathrm{.}50$ percent; and the cost of common equity $($in the form of retained earnings$)$ is $15\mathrm{.}50$ percent.

Calculate the Global Technology's weighted cost of each source of capital and the weighted average cost of capital.

Note: Do not round intermediate calculations. Input your answers as a percent rounded to $2$ decimal places.
