1. A manufacturer is considering a proposed (independent) capital investment in some equipment that has an initial investment of $60,000 and a useful life of five (5) years. Each year of the useful life, the investment will result in an operating return (operating cost savings) of $15,000. At the end of five years, the equipment will no longer be needed and can be sold for $6,000. (a) Draw and label the cash flow diagram. (b) If the firm has a minimum attractive rate of return (MARR) of 10%, compute the net present value and indicate whether or not the investment should be made
