a) Ball Bearings, Inc. can become profitable when the total revenue exceeds the total costs (variable and fixed). Ball's marginal cost is the additional cost that the corporation incurs for producing one additional unit of ball bearings. Its average fixed, variable, and total costs are computed by dividing the total fixed, variable, and total costs by the number of ball bearings produced.
