You have been asked by the president of your company to evaluate proposed project involving a spectrometer. The equipment's base price is $140,000, and it would cost another $30,000 to modify it for special use by your firm. The spectrometer, which falls into the MACRS 3-year class, would be sold after 3 years for $60,000. The applicable depreciation rates are 33 percent, 45 percent, 15 percent, and 7 percent. Use of the equipment would require an increase in net operating working capital (spare parts inventory) of $8,000. The spectrometer would bring in $100,000 in revenue per year for each of three years with $50,000 per year in operating costs per year. The firm's marginal federal-plus-state tax rate is 25 percent. (3 year Project – Find cash flows for 3 years)

If the project’s cost of capital is 12 percent, find the all cash flows, NPV and MIRR for the project ?
