You must evaluate a proposal to buy a new milling machine. The base price is $182,000, and shipping and installation costs would add another $13,000. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $91,000. The applicable depreciation rates are 33%, 45%, 15%, and 7%. The machine would require a %4,500 increase in net operating working capital (increased inventory less increased accounts payable).

Also, the firm spent $5,000 last year investigating the feasibility of using the machine
