Suppose the services of a road are subject to congestion after 50,000 vehicles per hour enter the road. Assume that it is feasible to price road services on an hourly basis. Create a graph similar to the one in Figure 4.2 of the textbook to show how the services of the road, in an effort to achieve efficiency, should be priced per hour when fewer than and more than 50,000 vehicles per hour are expected. Explain your answer. Create a graph on a spreadsheet program (such as MS Excel)
