You plan to invest in a project that will require you to make a total of six $30,000 payments over five years; the first payment is to be made today. After the payments end, the investment will grow for another 15 years.

If you require a 7.0% return on this investment, how much do you believe your investment will be worth at the end of the period?

Now consider what rate of return you will need to earn on the payments during the final 15 years of the investment if you want the amount of your investment to be 10% higher that the future value you just found.
