At this quantity, the marginal cost of the final romper they produce is $ , an amount 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 than the price received for each romper they sell. Therefore, Rian's profit-maximizing quantity occurs at the point of intersection between the curves. Because Rian is a price taker, the previous condition is equivalent to
