Suppose that JB Cos. has a capital structure of $78$ percent equity, $22$ percent debt, and that its before$-$tax cost of debt is $10$ percent while its cost of equity is $14$ 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? $($Round your answer to $2$ decimal places.$)$
