A university student painter is considering the purchase of a new air compressor and paint gun to replace an old paint sprayer. (Both items belong to Class 9 and have a 25 percent CCA rate.) These two new items cost $12,000 and have a useful life of four years, at which time they can be sold for $1,600. The old paint sprayer can be sold now for $500 and could be scrapped for $250 in four years. The entrepreneurial student believes that operating revenues will increase annually by $8,000. The tax rate is 22 percent and the required rate of return is 15 percent.
