Corcoran Consulting is deciding which of two computer systems to purchase. It can purchase state-of-the-art equipment (System A) for $20,000, which will generate cash flows of $5,000 at the end of each of the next 6 years. Alternatively, the company can spend $11,000 for equipment that can be used for 3 years and will generate cash flows of $5,000 at the end of each year (System B).
