Q. Christopher's cranks use a machine which can produce 100 cranks per hour. The industry operates 12 hrs per day, five days per week. Due to regularly scheduled preventive maintenance, the industry expects the machine to be running during approximately 95 percent of available time. Depend on experience with other products; the industry expects to achieve an efficiency level for the cranks of 85percent. Illustrate what is the expected weekly o/p of cranks for this company?
