Antonio's profit is maximized when he produces frying pans. When he does this, the marginal cost of the last frying pan he produces is $ , which is than the price Antonio receives for each frying pan he sells. The marginal cost of producing an additional frying pan (that is, one more frying pan than would maximize his profit) is $ , which is than the price Antonio receives for each frying pan he sells. Therefore, Antonio's profit-maximizing quantity corresponds to the intersection of the curves. Because Antonio is a price taker, this last condition can also be written as
