Answer:
The present worth of these benefits at an interest rate of 10% per year compounded semiannually is $11,193,231.
Explanation:
Future Value of Benefit = FV = 15 Million
Interest rate = r = 10% = 0.10 per year = 0.10 /2 = 0.05 semiannually
Number of years = 3 years
Compounding = Semiannually
Number of periods = n = 3 x 2 = 6
Present value of benefit is calculated using Following formula
PV = FV / ( 1 + r )^n
PV = $15,000,000 / ( 1 + 0.05 )^6
PV = $15,000,000 / ( 1.05 )^6
PV = $15,000,000 / 1.34
PV = $11,193,231
