Question
A replacement electricmotor is being considered for purchase. It is capable of providing 176.68 hp.
The data:
Cost | $3,178.65 |
Maintenance cost per year | 201.74 |
Useful Life | 14 years |
Salvage value | $2,135.30 |
The motor is used for 400 hours/year and the cost of electricity is $0.06/kW*h (1 hp = 0.746 kW). What is most nearly the present worth using an interest rate of 10%?
