You must evaluate the purchase of a proposed spectrometer for the R8D department. The base price is $160,000, and it would cost another $24,000 to modify the equipment for special use by the firm. The equipment falls into the MACRS 3 -year class and would be sold after 3 years for $48,000. The applicable depreciation rates are 33%,45%,15%, and 7%. The equipment would require an $8,000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $40,000 per year in before-tax labor costs. The firm's marginal federal-plus-state tax rate is 40%. The data has been collected in the Microsoft Excel Online file below. Open the spreadsheet and perform the required analysis to answer the questions below
