Madison's profit is maximized when they produce a total of rompers. At this quantity, the marginal cost of the final romper they produce is, an amount less than the price received for each romper they sell. At this point, the marginal cost of producing one more romper (the first romper beyond the profit maximizing quantity) is, an amount greater than the price received for each romper they sell. Therefore, madison's profit-maximizing quantity occurs at the point of intersection between themarginal cost and marginal revenue curves. Because madison is a price taker, the previous condition is equivalent to
