Answer:
15.85%
Step-by-step explanation:
The return on equity can be calculated using the Capital Asset Pricing Model:
Required Return on Equity = Risk free rate + Risk Premium
Now the economist say that using the cost of debt over risk free rate for estimating the cost of equity is better than using risk free rate. So the equation under this scenario becomes:
Required Return on Equity = Cost of debt + Risk Premium
Now by putting values, we have:
Required Return on Equity = 12% + 3.85% = 15.85%
