6. (15 points) At time zero (t = 0), a project requires a $90,000 initial investment in equipment and a $10,000 initial investment in working capital. You anticipate that the project will generate revenues of $120,000 per year for three years. You predict that manufacturing expenses will account for 60% of revenues. Assume that all income and expenses (i.e., t = 1, t = 2, and t = 3) occur at year's end. Over the three-year period, the equipment depreciates utilizing straight-line depreciation. The company can sell the equipment for \$10,000 at the end of the project and recover its investment in net working capital. The cost of capital is 15%, and the corporation tax rate is 21%. Calculate the project's NPV.
