Draw a monopolistic firm that is maximizing profit. Include MC, MU, and a downward-sloping MR that is left of the MU curve. Label the axes. Label the y-axis at the points where MC=MU and call it PC. Identify the point where MC=MR and draw a line from that point up to the MU curve (the demand curve). Identify where Qm would touch the MU curve and label the point on the y-axis PM.
