The weekly output of a production process is shown below, together with data for labor and material inputs. The standard inventory value of the output is $$125$ per unit. Overhead is charged weekly at the rate of $$1500$ plus $\mathrm{.}5$ times direct labor cost. Assume a $40-$hour week and an hourly wage of $$16.$ Material cost is $$10$ per running foot. Determine the multi$-$factor productivity for each week?
