Answer and Explanation:
The computation is shown below:
a. The expected return of equity is
= Expected return + debt to equity ratio × (expected return - debt cost to capital)
= 15.2% + 0.5 × (0.152 - 0.05)
= 20.3%
b. Now the debt cost of capital is 7%
So, the expected return of equity is
= Expected return + debt to equity ratio × (expected return - debt cost to capital)
= 15.2% + 0.5 × (0.152 - 0.07)
= 27.5%
c. As we know that if the investment has a higher return than of course it has high risk also or we can say it is compensated by high risk
So it would be best shareholder interest
