Using a graph, explain why a firm might not want tospend A on advertising, even though it shifts the firm'sdemand curve to the right.In the figure to the right, let Dand MR' be demand andmarginal revenue before advertising. Assume themonopoly has a constant marginal cost with no fixed costsuch that MR'= AC'Then, suppose the monopolyadvertises and that the advertising shifts demand andmarginal revenue to D? and MR?Assume advertising is a marginal cost, such that the newmarginal cost after advertising is still a constant and stillequals a new average cost.Using the line drawing tool, graph the marginal costcurve, reflecting the cost of the advertising, such that themonopoly breaks even from advertising. Label this curve"McZCarefully follow the instructions above, and only draw therequired objects
