7. 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 200 180 160 140 120 A 100 berand 05 19 15 20 25 30 35 550 QUANTITY (U) Graph Input Tool Market for Goods Quantity Demanded (Units) Demand Price (Dollars per unit) 25 100.00 2500 2250 1750 1250 1000 250+ རྞ ིི རྞ ༞ ཎཱ ཎྜ ཎྜ ༞ སྠཽ ིི་ . 5 10 15 20 25 30 QUANTITY (Number of units) Total Revenue 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 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 $93 Calculate the total revenue if the firm produces 20 versus 19 units. Then, calculate the marginal revenue of the 20th unit produced. The margnal revenue of the 20th unit produced is $33 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 plet the firm's marginal revenue curve on the following graph The marginal revenue of the 10th unit produced is $93 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 $33 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's marginal revenue curve on the following graph.

Comparing your total revenue graph to your marginal revenue graph, you can see that total revenue is marginal revenue is equal to zero. minimized maximized equal to zero at the output at which
