Assume a perfectly competitive market structure for rompers with a market price equal to $20 per romper. The following graph shows Madison's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for rompers for quantities zero through seven (including zero and seven) that Madison produces 200 175 150 125 3 4 QUANTITY (Rompers) Total Cost Total Revenue Profit 2
