Suppose that JB Companys has a capital structure of $75$ percent equity, $25$ percent debt, and that its before$-$tax cost of debt is $11$ percent while its cost of equity is $15$ percent. Assume the appropriate weighted$-$average tax rate is $21$ percent and JB estimates that they can make full use of the interest tax shield.

What will be JB$$s WACC?

Note: Round your answer to $2$ decimal places.
