3. You must evaluate the purchase of a proposed spectrometer for the R\&D department. The base price is $140,000, and it would cost another $30,000 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 $60,000. The applicable depreciation rates are 33%,45%,15%, and 7%, as discussed. 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 $50,000 per year in before-tax labor costs. The firm's marginal federal-plus-state tax rate is 35%. a. What is the initial investment outlay for the spectrometer, that is, what is the Year 0 project cash flow? b. What are the project's annual cash flows in Years 1,2 , and 3 ? c. If the required rate of return is 9%, should the spectrometer be purchased? Explain
