Use the graph to answer the following questions. 40,000 30,000 0 20,000 10,000 Uni ts 600 (a) Will the 201st item or the 601st item cost more to produce? Explain. The 201st unit will cost than the 601st unit, since C'(200) is than C'(600), and the slope gives the cost of the next unit. (b) Does this total cost function represent a manufacturing process that is getting more efficient or less efficient? Explain. The manufacturing process is becoming efficient. Since the slope is , the cost of each additional unit is than the previous unit. Need Help?
