You must evaluate the purchase of a proposed spectrometer for the R&D department. The purchase price of the spectrometer including modifications is $$280,000,$ and the equipment will be fully depreciated at the time of purchase. The equipment would be sold after $3$ years for $$41,000.$ The equipment would require a $$5,000$ increase in net operating working capital $($spare parts inventory$).$ The project would have no effect on revenues, but it should save the firm $$31,000$ per year in before$-$tax labor costs. The firm's marginal federal$-$plus$-$state tax rate is $25\%.$
