Answer:
WACC is 8.554%
Explanation:
First of all we will find Ke which can be calculated using the Capital Asset Pricing Model. The formula is as under:
Ke = Rf + β (Rm - Rf)
By putting the formula, we have:
Ke = 3.8% + 1.3 (8.4% - 3.8%)
Ke = 3.8% + 5.98% = 9.78%
Now after cost of debt = 8.5% * (1 - 21% tax rate) = 6.715%
Furthermore, we know that the Debt is 40% of total finance which means that the equity is 60%.
By putting value in the formula given in the attachment, we have:
WACC = (60% / 100%) *9.78% + (40% / 100%) * 6.715%
WACC = 8.554%
