Suppose JYP Electric opens a new plant in Orlando in response to rising economic freedom in that region. JYP hires 40 people to produce power cords in this plant and pays each worker an average piece work wage of $1,200 per week. Suppose JYP's workers combined can produce 4,000 power cords per week. What is the average product of labor for this plant? What is the average variable cost for this plant?
