The Crescent Company is considering the purchase of a new machine costing $200,000. This machine is estimated to cost $5,000 per year in operating expenses but it will allow the company to earn an additional $100,000 per year in revenues. However, on average, only 75% of sales are collected in the year of the sale, the remaining 25% are collected in the following year. At the end of 3 years the machine will have a salvage value of $10,000. If the required rate of return is 10% what is the net present value of this project.
