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, 4,
8, 10, 12, 16, and 20 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.
