An integrated, combined cycle power plant produces 285 MW of electricity by gasifying coal. The capital investment for the plant is $450 million, spread evenly over two years. The operating life of the plant is expected to be 18 years. Additionally, the plant will operate at full capacity 76% of the time (downtime is 24% of any given year). The MARR is 10% per year. a. If this plant will make a profit of two cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant? Is it a low-risk venture? b. What is the IRR for the plant? Is it profitable? a. The simple payback period of the plant is years. (Round up to one decimal place.) It's a venture. b. The IRR for the plant is%. (Round to one decimal place.) The plant is
An in place machine has an equivalent annual worth of $-100000 for each year of its maximum remaining useful life of two years. A suitable replacement is determined to have equivalent annual worth values of $-175000, $-125000, and $-150000 per year if kept for 1,2, or 3 years, respectively. When should the company replace the machine, if it uses a fixed 3-year planning horizon? Use an interest rate of 17.255609824% per year compounded semiannualy.
A large standby electricity generator in a hospital operating room has a first cost of $71,750 and may be used for a maximum of 6 years. Its salvage value, which decreases by 15% per year, is described by the equation S-71,750(1- 0.15), where n is the number of years after purchase. The operating cost of the generator will be constant at $9,250 per year, and the interest rate is 12% per year. Determine the economic service life and associated AW values. The economic service life is years and the AW value is $-

3) Find the rate of return (IRR-Ch16.3) on a project that will cost $100,000 today and $400,000 in 3 years from today, BUT will return $50,000 at the end of every year for 11 years (4)
Problem 03.043- Shifted gradients A software company that installs systems for inventory control using RFID technology spent $680,000 per year for the past 3 years in developing their latest product. The company optimistically hopes to recover its investment in 5 years on a single contract beginning immediately (year 0). The company is negotiating a contract that will pay $255,000 now and a to-be-agreed-upon annual increase of a constant amount each year through year 5. How much must the income increase (an arithmetic gradient) each year if the company wants to realize a return of 15 00% per year? (Round the final answer to three decimal places)
