A painter is considering the replacement of an old air compressor. The new items cost $8,000 and have a useful life of 4 years, at which time they can be sold for $1,100. The old compressor can be sold today for $300. It will be worth $150 in four more years. The painter believes that his revenue will go up by $8,000 per year with the new equipment. If the firm has a 22% tax rate, the equipment has a CCA rate of 25% and the owner wants a 17% return, what is the NPV?
