You must evaluate the purchase of a proposed spectrometer for the R\&D department. The base price is $210,000, and it would cost another $52,500 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 $73,500. The applicable depreciation rates are 33%,45%,15%, and 7%. The equipment would require an $12,000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $22,000 per year in before-tax labor costs. The firm's marginal federal-plus-state tax rate is 40%.
