Answer: 5.48%
Step-by-step explanation:
Total capital = 14 + 72 = $86
Weight of equity = 14/86
Weight of debt = 72/86
WACC = (Weight of debt * Cost of debt * ( 1 - tax)) + (Weight of equity * cost of equity)
= (72/86 * 5.34% * (1 - 28.94%)) + (14/86 * 14.16%)
= 0.0317687776744186 + 0.02305116279
= 5.48%
