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 DO 80 Quantity Demanded (Units) Demand Price (Dollars per unit) 70 50.00 00 PRICE (Dolars per unin 50 40 20 Demand 19 0 D 5 10 18 20 25 30 35 40 45 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 o, 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 1125 1000 Total Revenue 075 750 TOTAL REVENUE (Dollars 500 375 250 125 0 40 45 10 15 20 25 30 QUANTITY (Number of units) Calculate the total revenue of the fom produces 10 versus 9 units. Ther, calculate the maroval revenue of the 10th ur produced The marginal revenue of the 10th unit produced is Calculate the total revenue of the firm produces 20 versus 19 units. Ther, calculate the marginal revenue of the 20th un produced The marginal revenue of the 20th unit produced iss 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. (Round all values to the nearest increment of 20.) 100 30 Marginal Revenue 00 MARGINAL REVENUE (Dolars) 40 5 10 15 45 50 2025 30 38 QUANTITY (Units) Comparing your total revenue graph to your marginal revenue graph, you can see that when total revenue is increasino, marginal revenue is
