Calculating Project NPV

Who Dat Restaurant is considering the purchase of a $39,000 souffle maker. The souffle maker has an economic life of six years and will be fully depreciated by the straight-line method. The machine will produce 2,500 souffles per year, with each costing $2 to make and priced at $7. Assume that the discount rate is 14 percent and the tax rate is 34 percent. Should the company make the purchase?
