Answer:
10.45 %
Explanation:
Calculation for What is the cost of debt
Using this formula
Levered cost of equity=Unlevered cost of equity+Equity multiplier(1-Tax rate)(Unlevered cost of equity-Cost of debt)
Let plug in the formula
.156 = .14 + .57(1 −.21)(.14 − Cost of debt )
.156 = .14 + .57(.79)(.14 − Cost of debt )
Cost of debt= .1045 *100
Cost of debt= 10.45%
Note that equity multiplier of 1.57 -1 will give us .57
Therefore the cost of debt will be 10.45%
