Exercise 15

A small company plans to spend $10,000 in year 2 and $10,000 in year 5. At an interest rate of effective 10% per year, compounded semiannually, the equation that represents the equivalent annual worth A in years 1 through 5 is:
a) A = 10,000( P / F ,10%,2)( A / P ,10%,5) + 10,000( A / F ,10%,5)
b) A = 10,000( A / P ,10%,4) _ 10,000( A / F ,10%,5)
c) A = 10,000( P / F ,5%,2)( A / P ,5%,10) + 10,000( A / F ,5%,10)
d) A = [10,000( F / P ,10%,5) + 10,000]( A / F ,10%,5)
