Pedro Spier, the president of Spier Enterprises, is considering two investment opportunities. Because of limited resources, he will be able to invest in only one of them. Project A is to purchase a machine that will enable factory automation; the machine is expected to have a useful life of five years and no salvage value. Project B supports a training program that will improve the skills of employees operating the current equipment. Initial cash expenditures for Project A are $113,000 and for Project B are $35,000. The annual expected cash inflows are $29,051 for Project A and $9,233 for Project B. Both investments are expected to provide cash flow benefits for the next five years.
