Answer: $690,044
Step-by-step explanation:
First calculate WACC.
Total capital = 10 + 8 = $18 million
WACC = (Weight of debt * after-tax cost of debt) + (weight of equity * cost of equity)
= (8/18 * 3%) + (10/18 * 15%)
= 9.67%
Using the WACC, find the present value of the cashflows for the next 5 years. This will be an annuity.
= 180,500 * (1 - (1 + r) ^-n)/r
= 180,500 * ( 1 - ( 1 + 9.67%) ^ -5)/9.67%
= $690,044.67
= $690,044
They should pay no more than this present value.
