A motor with a 200-horsepower output is needed in the factory for intermittent use. A Graybar motor costs $7000 and has an electrical efficiency of 90%. A Blueball motor costs $6000 and has an 85% efficiency. Neither motor would have any salvage value, since the cost to remove it would equal its scrap value. The annual maintenance cost for either motor is estimated at $500 per year. Electric power costs $0.12/kWh (1 hp = 0.746 kW). If an 18% interest rate is used in the calculations, what is the minimum number of hours the higher initial cost Graybar motor must be used each year to justify its purchase?

Letang Industrial Systems Company (LSC) is trying to decide between two different conveyor belt systems. System A costs $325,000, has a four-year life, and requires $121,000 in pretax annual operating costs. System B costs $405,000, has a sle-year life. and requires $115,000 in pretax annual operating costs. Suppose the company always needs a conveyor belt system when one wears out, it must be replaced. Assume the tax rate is 22 percent and the discount rate is 11 percent Calculate the EAC for both conveyor belt systems. (A negative answer should be Indicated by a minus sign. Do not round Intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) System A System D 11:36 AM/

Kingsville plans to buy a street-cleaning machine. A used cleaning vehicle will cost $80,000 and have a $10,000 salvage value at the end of its five year life. A new system with advanced features will cost $160,000 and have a $45,000 salvage value at the end of its five year life. The new system is expected to reduce labor hours compared with the used system. Current street cleaning activity requires the used system to operate 8 hours per day for 20 days per month. Labor costs $50 per hour and MARR is 12% per year. Find the breakeven labor hours for the new system. USE SOLVER FUNCTION IN EXCEL

Letang Industrial Systems Company (LISC) is trying to decide between two different conveyor belt systems. System A costs $335,000, has a four-year life, and requires $129,000 in pretax annual operating costs. System B costs $415,000, has a six-year life, and requires $123,000 in pretax annual operating costs. Both systems are to be depreciated straight-line to zero over their lives and will have zero salvage value. Whichever project is chosen, it will not be replaced when it wears out. The tax rate is 24 percent and the discount rate is 9 percent. Calculate the NPV for both conveyor belt systems. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) System A System B

Machine A costs $1,520,000 to buy and install and costs $48,000 per year to operate. The machine has a five-year useful life and zero salvage value. The required return is 15.5%. What is the equivalent annual cost of Machine A? (Answer: $506,819)

Rust Industrial Systems Company is trying to decide between two different conveyor belt systems. System A costs $295,000, has a four-year life, and requires $77,000 in pretax annual operating costs.

Hagar Industrial Systems Company (HISC) is trying to decide between two different conveyor belt systems. System A costs $325,000, has a 4-year life, and requires $121,000 in pretax annual operating costs. System B costs $405,000, has a 6-year life, and requires $115,000 in pretax annual operating costs. Both systems are to be depreciated straight-line to zero over their lives and will have zero salvage value. Suppose the company always needs a conveyor belt system; when one wears out, it must be replaced. Assume the tax rate is 22 percent and the discount rate is 11 percent. Down Under Boomerang, Inc., is considering a new 3-year expansion project that requires an initial fixed asset investment of $2.29 million. The fixed asset falls into the 3-year MACRS class (MACRS schedule). The project is estimated to generate $1,810,000 in annual sales, with costs of $700,000. The project requires an initial investment in net working capital of $450,000, and the fixed asset will have a market…
