Evaluate a combined cycle power plant on the basis of the present worth method when the MARR is 12% per year. Pertinent cost data are as follows: Power Plant (in hundred thousand of P) P 13,000 15 years Investment cost Useful life Market Value (end P 3,000 of year 15) Annual operating P 1,000 expenses Overhaul cost – end P 200 of 5th year Overhaul cost – end P 550 of 10th year
A remotely located air sampling station can be powered by solar cells or by running an electric line to the site and using conventional power. Solar cells will cost $19,000 to install and will have a useful life of 4 years with no salvage value. Annual costs for inspection, cleaning, etc. are expected to be $1,100. A new power line will cost $9,000 to install, with power costs expected to be $800 per year. Since the air sampling project will end in 4 years, the salvage value of the line is considered to be zero. At an interest rate of 14% per year, which alternative should be selected on the basis of a future worth analysis? The future worth of solar cells is $ and that of electric line is $ Electric line should be selected on the basis of a future worth analysis.

A company plans to finance a large project that will last 5 years. The company will borrow $480,000 now to finance the project. How much will the company have to receive in annual payments for 5 years, provided it will also receive a final lump sum payment after 10 years in the amount of $50,000. The MARR is 20% per year on this investment. Your Answer: Answer units
A firm is must choose to buy the GSU-3300 or the UGA-3000. Both machines make the firm's production process more efficient which in turn increases incremental cash flows. The GSU-3300 produces incremental cash flows of $25,025.00 per year for 8 years and costs $102,242.00. The ÚGA-3000 produces incremental cash flows of $27,530.00 per year for 9 years and cost $126,773.00. The firm's WACĆ is 8.37%. What is the equivalent annual annuity of the GSU-3300? Assume that there are no taxes.
