Calculate Rian's marginal revenue and marginal cost for the first seven cardigans 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. 40 35 Marginal Revenue 30 O 25 Marginal Cost 20 COSTS AND REVENUE (Dollars per cardigan) 15 10 QUANTITY (Cardigans) Rian's profit is maximized when they produce a total of cardigans. At this quantity, the marginal cost of the final cardigan they produce is $, an amount than the price received for each cardigan they sell. At this point, the marginal cost of producing one more cardigan (the first cardigan beyond the profit maximizing quantity) is $ , an amount than the price received for each cardigan 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
