Answer:
a. 8.15%
Explanation:
In order to find the WACC we will multiply the cost of each type of capital source and multiply it by it's weight
Common Equity = Weight of equity * Cost of equity
=0.55*0.1125=0.061875=6.1875%
Preferred stock= Weight of preferred stock*yield of preferred stock
0.10*0.06=0.006= 0.6%
Debt= Weight of debt*interest rate*(1-tax rate)
=0.35*0.065*(1-0.4)
=0.01365=1.365%
Add all of these to find WACC
6.1875+1.365+0.6= 8.15%
