PowerTransfer makes large precision gears for heavy equipment. These are made by drop forging, and they have two identical drop forges. Currently, there are five gears that must be finished by tomorrow morning. The company only has one shift of workers but will pay them overtime to finish the gears. All workers in the shift stay until all jobs are completed. The times to process the five jobs are 3, 7, 2, 15, and 4 hours, respectively. What schedule would you recommend for this project? Explain.
