Calculate Iyana's marginal revenue and marginal cost for the first seven rompers they produce, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity. COSTS AND REVENUE (Dollars per romper) 40 35 30 25 20 15 10 0 0 1 2 3 4 5 6 7 8 QUANTITY (Rompers) Marginal Revenue Marginal Cost ? Iyana's profit is maximized when they produce a total of is $ , an amount rompers. At this quantity, the marginal cost of the final romper they produce 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, Iyana's profit-maximizing quantity occurs at the point of intersection between the Because Iyana is a price taker, the previous condition is equivalent to curves.
