Assume everything is given in n=0, CONSTANT dollars unless otherwise stated: Hartsfield Company is considering purchasing a set of machine tools at a cost of $80,000. The purchase is expected to generate revenues of $28,000. The purchase of the tools will also lead to higher operating costs of $6,000 per year in each of the next three years. Additional profits will be taxed at a rate of 30%. The asset falls into CCA Class 45 (rate = 40%) for tax purposes and the 50% rule applies. The project has a three-year life. The constant-dollar market (re-sale) value of the machine tools is expected to fall by 30% annually. The company will require a working capital of $8,000 to be maintained in purchasing power over the lifetime of the project, and can be recovered at the time of the project's completion. The general inflation rate is 8% per year (and affects everything that it normally affects). Assume a MARR' =5%. (Remember to round up/down to whole dollar figures for EVERY entry in the income statement and cash flow statement. Solutions are also rounded to the nearest dollar. Note: 5 rounds up) Find the NPW of the project
