UW The weekly out rate of a production process is shown below, together with data for labor, material inputs, and energy. The overhead cost is charged weekly at the rate of 500 plus 0.25 times direct labor cost. Assume a 40-hour week and an hourly wage of $12. Material cost is $6.5 per running foot. The energy cost is $0.05 per kWh. What is the average multifactor productivity for this process?
