Answer:
8.05%
Explanation:
Calculation of the weighted average cost of capital of Wentworth's Five and Dime Store
Using this formula
WACC=(1/1+debt–equity ratio)(Cost of equity)+( debt -equity ratio/1+debt–equity ratio)(Aftertax cost of debt)(1-tax rate)
Let plug in the formula
WACC = (1/1.81)(.121) + (.81/1.81)(.05)(1 -.39)
WACC= (0.5524)(.121)+ (0.4475)(.05)(0.61)
WACC=0.0668404+0.01364875
WACC=0.080489×100
WACC=8.05% Approximately
Therefore the weighted average cost of capital of Wentworth's Five and Dime Store will be 8.05%
