Economics 2. Relationship between total and marginal revenueSuppose there's an appliance store that produces and sells air conditioners. It could set its price high and sell veryfew air conditioners, or it could set its price low and sell lots of air conditioners. The following table shows somepossible choices this store could make for its annual production.ChoiceABCDEPrice$6004503001500DOLLARS (Thousands of dollars per year)6054The following graph plots the firm's "total revenue" curve: that is, the relationship between quantity and totalrevenue given by the two right columns in the previous table.

Therefore, the slope of the total revenue curve at any output levelapproximates the firm's. Note that the slope of the total revenue curve at any point isthe same as the slope of a line tangent to the total revenue curve at that point. The following diagram plots this firm's demand curve. Using the previous total revenue graph, calculate the slope ofthe lines tangent to the total revenue curve at points B and D. Based on this information, use the black line (Xsymbols) to plot the firm's marginal revenue (MR) curve on the graph.DOLLARS (Dollars per air conditioner)6805444082721360-136-272-408-544-680040Demand80 120 160 200 240 280 320OUTPUT (Air conditioners per year]Marginal Revenue-x-x-Help Clear AllThe total revenue curve reaches its maximum at a quantity ofmarginal revenue curve isair conditioners per year.
