35. In this problem, we need to calculate the future value of the annual savings after the five years of
operations. The savings are the revenues minus the costs, or:
Savings = Revenue – Costs
Since the annual fee and the number of members are increasing, we need to calculate the effective
growth rate for revenues, which is:
The revenue will grow at 9.18 percent, and the costs will grow at 2 percent, so the savings each year
for the next five years will be:
Now we can find the value of each year’s savings using the future value of a lump sum equation, so:
FV = PV(1 + r)t
Total future value of savings =
He will spend $500,000 on a luxury boat, so the value of his account will be:
Value of account = $1,373,279.31 – 500,000
