Five years from today he will begin paying you $2,500 a year for the next 4 years. The first payment occurs 5 years from today, and the total of the four payments will be $10,000. a. If your minimum ROR is 8%, then is this an acceptable investment? Explain. b. For the same payment schedule but with a 5% rate of inflation, is this an acceptable investment?
