Suppose eggs are only sold by the dozen and priced in whole dollar amounts. No eggs are demanded at a price above $7 per dozen. At a price equal to $7 per dozen, 10 dozen eggs are demanded. If the price falls to $6 per dozen, then 11 dozen are demanded. At a price of $5 per dozen, 12 dozen are demanded. When the price falls to $4 then 13 dozen are demanded. Suppose also that this market is operating in the short run and the quantity of eggs supplied is fixed at 12 dozen eggs. What are the equilibrium price and quantity in this market?
