The 101st unit will cost ---Select--- than the 501st unit, since C'(100) is ---Select--- | than C'(500), 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 |---Select--- ✓ efficient.
