Ball Bearings, Inc., faces costs of production as follows:
Quantity Total Fixed Cost Total Variable Cost
0 $100 $0
1 100 50
2 100 70
3 100 90
4 100 140
5 100 200
6 100 360 Calculate the company’s average fixed cost, average
variable cost, average total cost, and marginal
cost at each level of production.
b. The price of a case of ball bearings is $50. Seeing
that he can’t make a profit, the chief executive
officer (CEO) decides to shut down operations.
What is the firm’s profit/loss? Was this a wise
decision? Explain.
c. Vaguely remembering his introductory economics
course, the chief financial officer tells the CEO
it is better to produce 1 case of ball bearings,
because marginal revenue equals marginal cost
at that quantity. What is the firm’s profit/loss
at that level of production? Was this the best
decision? Explain.
