A California utility firm is considering building a 50-megawatt geothermalplant that generates electricity from naturally occurring underground heal. The binary geothermal system will cost $85 million to build and $6 million (including any income-tax effect) to operate per year. (Unlike a conventional fossilfuel plant, this system will require virtually no fuel costs.) The geothermal plant is to last 25 years. At the end of that time, the expected salvage value will be about the same as the cost to remove the plant. The plant will be in operation for 70% (the plant-utilization factor) of the year (or 70% of 8,760 hours per year). If the firm's MARR is 14% per year, determine the cost of generating electricity per kilowatt-hour.

Covington Corporation purchased a vibratory finishing machine for $20,000 in year 0. The useful life of the machine is 10 years, at the end of which the machine
is estimated to have a salvage value of zero. The machine generates net annual revenues of $6,000. The annual operating and maintenance expenses are
estimated to be $800. If Covington's
MARR is 16%, how many years will it take before this machine becomes profitable? Assume that the cash flows occur continuously throughout the year.
It will take years before this machine becomes profitable. (Round to one decimal place.)

- Your company is considering purchasing a new CNC machining center. The net benefits in the first year will be $50,000, increasing at a rate of $4,000 per year for the subsequent nine years (so the benefits are $50,000, $54,000, $58,000, etc.). You think the company can get a salvage value of $18,000 at the end of its 10-year useful life. If the MARR is 8%, how much can the company justify spending on the CNC machining center? Solve by present worth analysis.arrow_forwardA new utility service truck can be purchase for $70,043. Its expected useful life is six years, at which time its market value will the zero. Annual receipts less expenses will be approximately $28,084 per year over the six-year study period. Compute Present Worth (PW) with a MARR of 20% to determine whether this is good investment.arrow_forwardA company is considering constructing a plant to manufacture a proposed new product. The land costs $250,000, the building costs $650,000, the equipment costs $300,000, and $80,000 additional working capital is required. It is expected that the product will result in sales of $700,000 per year for 11 years, at which time the land can be sold for $350,000, the building for $400,000, and the equipment for $50,000. All of the working capital would-be recovered at the EOY 11. The annual expenses for labor, materials, and all other items are estimated to total $500,000. If the company requires a MARR of 14% per year on projects of comparable risk, determine if it should invest in the new product line. Use the AW method.
