The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $940,000, and it would cost another $19,500 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $561,000. 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 $17,000, The sprayer would not change revenues, but it is expected to save the firm $341,000 per year in before-tax operating costs, mainiy labor.
