The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $88 and it would cost another $21,000 to install it. The machine falls into the MACRS 3-year class (the applicable MACRS depr rates are 33.33%,44.45%,14.81%, and 7.41% ), and it would be sold after 3 years for $624,000. The machine would rea increase in net working capital (inventory) of $12,000. The sprayer would not change revenues, but it is expected to save $458,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 35%.
