2. Calculating marginal revenue from a linear demand curve The blue curve on the following graph represents the demand curve facing a firm 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 field, the graph and any corresponding amounts in each grey field will change accordingly. Graph Input Tool 100 Market for Goods 90 I Quantity Demanded 25 (Units 70 Demand Price (Dollars per unit) 50.00 60 50 PRICE (Dollars per unit) 30 Demand 20 10 0 5 10 15 20 25 30 35 40 4 50 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, 10, 20, 25, 30, 40, and 50 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. 1250 A 1125 Total Revenue 1000 375 750 TOTAL REVENUE (Dollars) 625 500 375 250 125 5 10 15 20 25 30 35 40 45 50 QUANTITY (Number of units)Calculate the total revenue if the firm produces 10 versus 9 units. Then, calculate the marginal revenue of the 10th unit produced. The marginal revenue of the 10th unit produced is . Calculate the total revenue if the firm produces 20 versus 19 units. Then, calculate the marginal revenue of the 20th unit produced. The marginal revenue of the 20th 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's marginal revenue curve on the following graph. ( Round all values to the nearest increment of 20. ) 100 80 Marginal Revenue 60 MARGINAL REVENUE (Dollars) 40 20 -20 5 10 15 20 25 30 35 40 45 50 QUANTITY (Units) Comparing your total revenue graph to your marginal revenue graph, you can see that when total revenue is increasing, marginal revenue is10 15 20 25 30 3-5 40 45 50 QUANTITY (Units) equal to zero negative positive total revenue graph to your marginal revenue graph, you can see that when total revenue is increasing, marginal revenue is v
