Problem 11-7 New-Project Analysis The president of the company you work for has asked you to evaluate the proposed acquisition of a new chromatograph for the firm's R&D department The equipment's basic price is $90,000, and it would cost another $22,500 to modify it for special use by your firm. The chromatograph, which falls into the MACRS 3-year class, would be sold after 3 years for $40,500. Use of the equipment would require an increase in net working capital (spare parts inventory) of $4,500. The machine would have no effect on revenues, but it is expected to save the firm $36,000 per year in before-tax operating costs, mainly labor. The firm's marginal federal-plus-state tax rate is 40%. a. What is the Year-0 net cash flow? If the answer is negative, use minus sign. b. What are the net operating cash flows in Years 1, 2, and 3?
