2. Calculating marginal revenue from a linear demand curve The blue curve on the following graph represents the demand curve facing a rm that can set its own prices. Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph. Note: Once you enter a value in a white eld, the graph and any corresponding amounts in each grey field will change accordingly. Graph Input Tool Market for Goods | Quantity Demanded II] (Units) Demand Price (Dollars per unit) 75'00 PRICE (Dollars per unit) 9 12 15 18 21 24 27 30 QUANTITY (Units) On the graph input tool, change the number found in the Quantity Demanded field to determine the prices that correspond to the production of 0, 6, 12, 15, 18, 24, and 30 units of output. Calculate the total revenue for each of these production levels. Then, on the following graph, use the green points (triangle symbol) to plot the results. 1130 A 1017 904 Total Revenue 791 678 TOTAL REVENUE (Dollars) 565 452 339 226 113 0 6 9 12 15 18 21 24 27 30 QUANTITY (Number of units)Calculate the total revenue if the rm produces 6 versus 5 units. Then, calculate the marginal revenue of the sixth unit produced. The marginal revenue of the sixth unit produced is $ Calculate the total revenue if the rm produces 12 versus 11 units. Then, calculate the marginal revenue of the 12th unit produced. The marginal revenue of the 12th unit produced is $ . Based on your answers from the previous question, and assuming that the marginal revenue curve is a straight line, use the black line (plus symbol) to plot the rm '5 marginal revenue curve on the following graph. (Round all values to the nearest increment of 30.) Based on your answers from the previous question, and assuming that the marginal revenue curve is a straight line, use the black line (plus symbol) to plot the firm '5 marginal revenue curve on the following graph. (Round all values to the nearest increment of 30.) 150 -- + 120 Marginal Revenue (a D MARGINAL REVENUE (Dollars) 8 8 I : 0 3 6 9 12 15 18 21 24 27 30 QUANTITY (Units) Comparing your total revenue graph to your marginal revenue graph, you can see that when total revenue is increasing, marginal revenue is v -30 6 9 12 15 18 21 24 27 30 negative QUANTITY (Units) positive equal to zero total revenue graph to your marginal revenue graph, you can see that when total revenue is increasing, marginal revenue is
