Identify the curve that represents the RAM motor and hence determine the range of the number of operating hours for which it is the most economical of the three motors. O A. between 500 and 1,500 O B. less than 900 O C. more than 1,500 O D. less than 500 O E. between 900 and 1,500 OF. more than 900 O G. between 500 and 900Three motors are being evaluated for use in a factory. The information is summarized in the table below. The accompyning chart shows the Equivalent Uniform Annual Costs (EUAC) of the motors as a function of the number of operating hours per year. COLT RAM JET EUAC EUAC vs Operating hrs/yr Initial price $2,000 $1,000 $300 $3,500 Efficiency 89% 74% 60% Annual cost $145 $200 $300 $3,000 Life (yrs) $2,500 $2,000 $1,500 $1,000 $500 Operating hrs/yr SO 0 500 1000 1500 2000 Answer the following two questions: Identify the curve that represents the COLT motor and hence determine the range of the number of operating hours for which it is the most economical of the three motors.
