exe Exercise II Based on the following information for Project X, should we undertake the venture? Calculate the NPV assuming a 28 percent required return and a 21 percent tax rate. Project X involves a new type of graphite composite in-line skate wheel. We think we can sell 6,000 units per year at a price of 1,000 each. Variable costs will run about $400 per unit, and the product should have a four-year life. Fixed costs for the project will run $450,000 per year. Further, we will need to invest a total of $1,250,000 in manufacturing equipment. The depreciation amount is $312,500 each year. We will have to invest $1,150,000 in net working capital at the start. After that, net working capital requirements will be 25 percent of sales
