Suppose that TapDance, Incorporated$$s capital structure features $70$ percent equity, $30$ percent debt, and that its before$-$tax cost of debt is $7$ percent, while its cost of equity is $12$ percent. The appropriate weighted average tax rate is $21$ percent and TapDance estimates it cannot make any use of the interest tax shield in the foreseeable future.

What will be TapDance$$s WACC?
