Exercise 10

Use the information on the U.S. wholesale market for roses to Problem.
Wholesalers of roses (the firms that supply your local flower shop with roses for Valentine's Day) buy and sell roses in containers that hold 120 stems. The table provides information about the wholesale market for roses in the United States. The demand schedule is the wholesalers' demand and the supply schedule is the U.S. rose growers' supply.
Wholesalers can buy roses at auction in Aalsmeer, Holland, for $125 per container.
Draw a graph to illustrate the gains and losses from the import quota and on the graph identify the gains and losses, and the importers' profit.
