NEW PROJECT ANALYSIS You must evaluate the purchase of a proposed spectrometer for the R&D department. The base price is $90.000, and it would cost another $13,500 to modify the equipment for special use by the firm. The equipment falls into the MACRS 3-year dass and would be sold after 3 years for $45,000. The applicable depreciation rates are 33%, 45%, 15%, and 7%. The equipment would require a $11.000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $75,000 per year in before tax labor costs. The firm's marginal federal-plus-state tax rate is 40%. a.
