12.   As always, the equilibrium price is the price at which the desired quantity demanded and supplied are equal. At any price above equilibrium, the desired quantity demand will be greater than the desired quantity supplied. At any price below equilibrium, the desired quantity demand will be smaller than the desired quantity supplied.

   In the table, shown again to the right, there is no price at which demand and supply are equal. However, we can see that at prices of $3 and below, Quantity Demanded is greater than Quantity Supplied; but at prices of $4 and up, supply is greater than demand. This means that the equilibrium price has to lie between $3 and $4. The only price in that range is $3.40.
