2.       Draw graph to illustrate the difference between a decrease in the quantity demanded and a decrease in demand for Mickey Mantle baseball cards. Give a possible reason for change in each graph.

The decrease in the quantity demanded is a response to an increase in the price from P1 to P2   per Mickey Mantle baseball card. The decrease in demand from D1 to D2 is caused by a change in a nonprice determinant, such as a decrease in the number of buyers.

6. Explain why the market price may not be the same as the equilibrium price.

The market price moves by trial and error toward the equilibrium price. If the market price is above the equilibrium price, there will be a surplus. If the market price is below the equilibrium price, there will be a shortage. Itmay be just slow to adjust.  It could also have a price control and be prevented from being at the equilibrium price.
