Answer:
6.88%
Step-by-step explanation:
cost of equity = (next period dividend / by price) + growth rate in dividends.
cost of debt = yield to maturity x (1 - tax rate)
WACC = weight of debt x cost of debt + weight of equity x cost of equity.
cost of equity = ($0.25 / $40) + 0.07
= 0.07625
cost of debt = 0.09 x (1 - 0.4)
=0.054
WACC = ($40Billion x 0.07625) / 60billion + ($20 billion x 0.054) / $60billion
= 0.05083 + 0.018
= 0.0688 or 6.88%
