The city of Oak Ridge is considering the construction of a three kilometer (km) greenway walking trail. It will cost $1,000 per km to build the trail and $320 per km per year to maintain it over its 23-year life. If the city's MARR is 10% per year, what is the equivalent uniform annual cost of this project? Assume the trail has no residual value at the end of 23 years.
An integrated, combined cycle power plant produces 285MW of electricity by gasifying
coal. The capital investment for the plant is $570 million, spread evenly over two years.
The operating life of the plant is expected to be 20 years. Additionally, the plant will operate
at full capacity 75% of the time (downtime is 25% of any given year).
a. If this plant will make a profit of three 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?
Tabulate the net cash flow and the cumulative PW.
b. What is the IRR for the plant? Is it profitable?
Company X has been contracting its overhauling work to Company Y for$40,000 per machine per year. Company X estimates that by building a $500,000 maintenance facility with a life of 15 years and a salvage value of $100,000 at the end of its life, it could handle its own overhauling at a cost of only $30,000 per machine per year. What is the minimum annual number of machines that Company X must operate to make it economically feasible to build its own facility, assuming an interest rate of 10%?

- You are evaluating two different silicon wafer milling machines. The Techron I costs $228,000, has a three-year life, and has pretax operating costs of $59,000 per year. The Techron II costs $400,000, has a five-year life, and has pretax operating costs of $32,000 per year. For both milling machines, use straight-line depreciation to zero over the project’s life and assume a salvage value of $36,000. If your tax rate is 24 percent and your discount rate is 8 percent, compute the EAC for both machines. Note: Your answer should be a negative value and indicated by a minus sign.
