Rocky Mountain Lumber, Inc., is considering purchasing a new wood saw that costs $55,000. The saw will generate revenues of $100,000 per year for five years. The cost of materials and labor needed to generate these revenues will total $60,000 per year, and other cash expenses will be $10,000 per year. The machine is expected to sell for $1,100 at the end of its five-year life and will be depreciated on a straight-line basis over five years to zero. Rocky Mountains tax rate is 34 percent, and its opportunity cost of capital is 17.90 percent. What is the project's NPV?
