The problem is down below.

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 ? 50 Market for Goods 45 Quantity 25 Demanded 40 (Units) 35 Demand Price 25.00 (Dollars per unit) 30 25 PRICE (Dollars per unit) 20 15 Demand 10 0 5 10 15 20 25 30 35 40 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. 630 567 Total Revenue 504 441 378 315 TOTAL REVENUE (Dollars) 252 189 126 63 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 '5 marginal revenue curve on the following graph. (Round all values to the nearest increment of 10.) 50- .4}. 40 - Marginal Revenue 1.: c I MARGINAL REVENUE (Dollars) 'o' 8 0 5 1D 15 20 25 30 35 4D 45 5!)
