graph that depicts Joe's family restaurant in a perfectly competitive market. If price is P3, the profit-maximizing output A coordinate plane relates price, costs along the vertical axis to output along the horizontal axis, and represents three curves.The curve labeled M C intersects the curve labeled A T C at a point (Q3, P2) and the curve labeled A V C at a point (Q2, P1). The values P1, P2, P3, and P4 are marked on the vertical axis and the values Q1, Q2, Q3, and Q4 are marked on the horizontal axis. Multiple Choice equals Q4. is between Q3 and Q4. equals Q3. equals Q1
