It is estimated that an investment alternative with an
initial investment cost of 150000 TL will generate
annual revenues of 85000 TL and annual expenses of
20000 TL. It is expected to have a scrap value of 95000
TL at the end of its 5-year life. Find out how sensitive
the investment decision of this investment alternative
is to its revenues. (MARR: %10)
Two electric motors (A and B) are being considered to drive a centrifugal pump. Each motor is capable of delivering 40 horsepower (output) to the pumping operation. It is expected that the motors will be in use
800 hours per year. If electricity costs $0.08 per kilowatt-hour and 1 hp = 0.746 kW, which motor should be selected if MARR = 6% per year? Refer to the data below.

Be sure to list your steps. You are evaluating two different silicon wafer milling machines. The Techron I costs $237,000, has a three-year life, and has pretax operating costs of $62, 000 per year. The Techron II costs $ 415,000, has a five - year life, and has pretax operating costs of $ 35,000 per year. For both milling machines, use straight - line depreciation to zero over the project's life and assume a salvage value of $39, 000. If your tax rate is 21 percent and your discount rate is 8 percent, compute the EAC for both machines. (Your answer should be a negative value and indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)arrow_forward
