In order to establish a contingency fund to replace equipment after unexpected breakdowns, a manufacturer of thin-wall plastic bottles plans to deposit $100,000 now and $150,000 two years from now into an investment account. Assuming the account grows at 15% per year, the equation that does not represent the future value of the account in year 5 is:
(a) F = 100,000(F?P,15%,5) + 150,000(F?P,15%,3) (b) F = [100,000(F?P,15%,2) + 150,000] (F?P,15%,3) (c) F = [100,000 + 150,000(P?F,15%,2)] (F?P,15%,5) (d) F = 100,000(F?P,15%,5) + 150,000(F?P,15%,2)
