Explanation:

Weighted Average Cost of Capital (WACC) is the cost of capital for all company projects.It shows  the risk of the company.

WACC = Ke×(E/V) + Kp×(P/V) + Kd×(D/V)

           = 0.10 × 70% + 0.05 × 5% + 0.06 × 77%× 25%

           = 8.405 or 8.41 %

After tax cost of debt = Market Interest × ( 1 - tax rate)

                                   = 0.06 × (1 - 0.23)

                                   =  4.62 %
