Exercise 35

In comparing alternatives I and J by the present worth method, the equation that yields the present worth of alternative I is:
A)PW I = 150,000 + 11,000( P / A ,15%,3) + 25,000( P / F ,15%,3)
(b)PW I = 150,000 + 11,000( P / A ,15%,6) + 25,000( P / F ,15%,6)
C)PW I = 150,000 + 11,000( P / A ,15%,6) + 175,000( P / F ,15%,3) + 25,000( P / F ,15%,6)
D)PW I = 150,000 + 11,000( P / A ,15%,6) 125,000( P / F ,15%,3) + 25,000( P / F ,15%,6) The interest rate is 15% per year.
