A special-purpose 30-horsepower electric motor has an efficiency of 90%. Its purchase and installation price is $2,200. A second 30-horsepower high-efficiency motor can be purchased for $3.200. and its efficiency is 93%. Either motor will be operated 4,000 hours per year at full load, and electricity costs $0.10 per kilowatt-hour (kWh). MARR = 15% per year, and neither motor will have a market value at the end of the eight-year study period. Most motors are operated at a fraction of their rated capacity (i.e., full load) in industrial applications. Suppose the average usage (load factor) of motors is expected to be 60%. Which motor should be recommended under this condition? Click the icon to view the interest and annuity table for discrete compounding when i = 15% per year. The PW of the motor with the efficiency of 90% is $ (Round to the nearest dollar.) The PW of the motor with the efficiency of 93% is $ (Round to the nearest dollar.) Which motor should be chosen? Choose the correct answer below. gle O O 93% efficiency motor 90% efficiency motor panc n God
