Eric is considering an investment in a donut producing facility. This facility requires an investment of $100,000 at time 0. It will then produce revenues (in real terms) of $70,000, $60,000, $50,000, in years 1, 2, and 3, respectively. This process must be repeated indefinitely (that means forever). For example, in year 3, Eric would have to invest another $100,000 dollars and then get revenues (again in real terms) of $70,000, $60,000, $50,000, in years 4, 5, and 6, respectively. Eric's real MARR is 6% per year compounded yearly. a. Is this a good investment? Support your answer. b. What is the present value of this investment
