1.New instrumentation is needed to monitor the level of environmental emissions at a large manufacturing plant. Two available systems give identical performance. One system cost $100,000 and will last for 10 years; the other costs $60,000 and will last for 6 years. The scrap value is negligible in both cases. Both systems also have an annual maintenance cost of $1,000/year. Is one of the systems preferable to the other based on cost? Assume the company’s interest is 10 percent.
