1. 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 $1250 per unit. Overhead is charged weekly at the rate of $1500 plus .5 times direct labor cost. Assume a 40-hour week and an hourly wage of $16 per worker. Material cost is $10 per running foot. (Multi-factor inputs are considered overhead, labor, and material.)

a. What is the multi-factor productivity of Week 4?

b. What is the average multi-factor productivity for this process? $
