The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $870,000, afd it would cost another $25,000 to install it. The machine falls into the MACRS 3-year class, and it would be soid after 3 years for $509,000. The MACRS rates for the first three years are 0.3333,0.4445, and 0.1481 . The machine would require an increase in net working copital (inventory) of $16,000. The sprayer would not change revenues, but it is expected to save the firm $385,000 per year in before-tax operating costs, mainly labor, Campbeli's marginal tax rate is 25%.

What is the addional Year-3 cash flow (l.e, the after-tax salvage and the return of working capital)? 5 d. If the project's cost of capital is 10%, what is the NPV of the project? $ Should the machine be purchased
