Answer:
the weighted cost of capital is 10.16%
Explanation:
The computation of the weighted average cost of capital is as follows
The WACC is
= Cost of debt × weight of debt × (1 - tax rate) + weight of equity × cost of equity
where,
Weight of debt is
= $475 ÷ ($475 + $500)
= 0.487
Weight of equity is
= $500 ÷ ($475 + $500)
= 0.513
Cost of equity is
= Risk free rate + beta × market risk premium
= 5% + 1.15 × 9%
= 15.35%
Now the WACC is
= 7.85% × 0.487 × (1 - 0.40) + 0.513 × 15.35%
= 2.29% + 7.87%
= 10.16%
hence, the weighted cost of capital is 10.16%
