The East Coast University uses a printing machine, the FL200, to print exam papers. According to the operation manual, FL200 can prints 2000 sets of exam papers per hour when it is operating at peak efficiency. However, the printing manager notes that in normal (but still efficient) operations, the machine can produce only 1800 sets of exam papers in an hour. Further, she also notes that given the small number of students enrolled in the East Coast University, the machine is never required to print more than 1500 sets of exam papers per hour. The theoretical capacity of the FL200 is: a. 1500 sets of exam papers per hour. b. 1800 sets of exam papers per hour. c. 500 sets of exam papers per hour. d. 2000 sets of exam papers per hour.
