Amanda James is the chief operating officer for the Omega Corporation-a computer services firm that specializes in airborne support. The company is considering four capital investment projects for the next year. Only one of the four projects under consideration can be chosen. Amanda considers that all projects are equally risky and therefore used 8% as the minimum acceptable rate of return. The company uses a straight-line method for calculating depreciation and the company's tax rate is 33%. Proposal -A: This proposal is to add a jet to the company's fleet. The plane was only six years old and was considered a good buy at $300,000. In return, the plane would bring over $600,000 in additional revenue during the next five years with only about $56,000 in operating costs.
