- Draw a correctly labeled graph showing the market for tomatoes
in equilibrium. Label the equilibrium price “PE” and the
equilibrium quantity “QE.” On your graph, draw a horizontal line
indicating a price, labeled “PC”, that would lead to a shortage of
tomatoes. Label the size of the shortage on your graph.
