Essay

A $38,000 coil winding and unwinding machine is estimated to provide additional value to production by $15 per unit. When the machine is operated at 58 units per hour, it needs to be cooled down after 4 hours of operation and receive minor maintenance for 15 minutes. When the machine is operated at 118 units per hour, it needs to be cooled down after 5 hours of operation and receive minor maintenance for 30 minutes. The production line runs 8 hours per day. If each maintenance check costs $625 and the machine has a useful life of 80,000 hours of operations, at what speed should the machine should be operated?
