Garry Piper’s rich uncle gave him $80,000 cash as a gift for his 40th birthday. Unlike his spoiled cousins who spend money carelessly, Mr. Piper wants to invest the money for his future retirement. After an extensive search, he is considering one of two investment opportunities. Project 1 would require an immediate cash payment of $60,000; Project 2 needs only a $30,000 cash payment at the beginning. The expected cash inflows are $18,000 per year for Project 1 and $9,200 per year for Project 2. Both projects are expected to provide cash flow benefits for the next four years.
Mr. Piper found that the interest rate for a four-year certificate of deposit is about 5 percent. He decided that this is his required rate of return.
