a. Draw the production possibilities frontier (curve) for Travelville. Put airplanes (A) on the vertical axis. Assume that fractions of airplanes and buses can be built. (HINT: For different quantities of airplanes, determine how many buses can be produced. How many airplanes and buses can be produced if all resources are devoted to airplanes? If ten less airplanes are produced, how many buses can be produced? 20 less? Etc. Construct a table, and then graph it. It is helpful to include in your table the resources being devoted to the production of each good as well as the total amounts of labor and steel being used.)Airplanes (A)
