The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $970,000, and it would cost another $23,500 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $612,000. 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 capital (inventory) of $19,500. The sprayer would not change revenues, but it is expected to save the firm $316,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 25%.
