Hi I am having a hard time figuring this out

The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $930,000, and it would cost another $22,500 to install it. The machine falls into the MACRS 3-year class (the applicable MACRS depreciation rates are 33.33%, 44.45%, 14.81%, and 7.41%), and it would be sold after 3 years for $569,000. 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 $366,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 40%.
