Mmasodwo Enterprice is considering investing in a machine to produce computer keyboards. The price of the machine will be 530,000 and its economic life is five years. The machine will be fully depreciated by the straight-line method. The machine will produce 15,000 keyboards each year. The price of each keyboard will be 40 in the first year and will increase by 5 percent per year. The production cost per keyboard will be 20 in the first year and will increase by 6 percent per year. The project will have an annual fixed cost of 75,000 and require an immediate investment of 25,000 in net working capital. The corporate tax rate for the company is 34 percent. If the appropriate discount rate is 15 percent, what is the NPV of the investment? (15 marks)
