Assume there is a toll bridge that is built by a private firm. It's been determined by cost accountants that the marginal cost that each automobile imposes is close to zero

If the bridge cost $1 million to build and 250,000 automobiles cross it each day what is the price that would be necessary for the firm to charge in order to achieve the key efficiency criteria of perfect competition? How might this be a problem for this private bridge company?

The price would have to be equal to zero. This would equal to the marginal cost that each automobile imposes on the bridge. This would be a problem because the firm would not be able to stay in business.
