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% CCA rate.) These two new items cost $13,900 and have a useful life of four years, at which time they can be sold for $3,500. The old paint sprayer can be sold now for $690 and could be scrapped for $440 in four years. The entrepreneurial student believes that operating revenues will increase annually by $9,900. The tax rate is 22% and the required rate of return is 15%. What is the NPV of the new equipment? (Do not round intermediate calculations. Round the final answer to 2 decimal places. Omit $ sign in your response.) $ NPV Should the purchase be made? Yes O No
