Please show all work, and be sure to answer each part of every question. Be sure to label all axes and curves, and show numerical intercepts and intersection points where ever possible. Partial credit will be given where appropriate. Use extra pages if necessary. 1. Suppose that you open a restaurant that only serves chicken soup. You sell both cups of soup and bowls of soup. A cup of soup is made up of 5 fluid ounces of soup. A bowl of soup consists of 15 fluid ounces of soup. Suppose that you currently have a big pot of soup on the stove that contains 300 fluid ounces of soup. a. Draw the PPC for your restaurant. Put cups of soup on the vertical axis and bowls of soup on the horizontal axis. (4 points) b. On your graph, please show (i) an inefficient point, (ii) an efficient point, and (iii) an unattainable point. (3 points) c. What is the opportunity cost of one bowl of soup? (3 points) d.
