Answer: 11.65%
Step-by-step explanation:
First find cost of equity using CAPM:
= Risk free rate + Beta * Market risk premium
= 3.4% + 1.37 * 8.2%
= 14.6%
Debt to equity = 0.45
This means that weight of debt is:
= 0.45 / (1 + 0.45)
= 31.03%
Weight of equity:
= 1 - 31.03%
= 68.97%
WACC = (Weight of equity * cost of equity) + (weight of debt * cost of debt * (1 - tax))
= (68.97% * 14.6%) + (31.03% * 7.6% * (1 - 34%))
= 11.63%
= 11.65% as per options
