Study the following graphs and answer the questions following. (Don't forget that 
price is always the verticle value and when there are more than one curve
that the upper curve shows less supply.)

1. Does this graph show a change in Supply (s) or a change in Quantity Supply (qs)?
2. Explain the difference between values A and B. How many pies were were produced at what price?

3. Does this graph show a change in Supply (S) or a change in Quantity Supply (qs)?
4. If the two supply curves indicate the production of strawberry pies, explain the 
difference if the production factor involved the cost of strawberries.
5. Does the price of the pies make any difference at all in the two curves?

7. If the two supply curves indicate the production of strawberry pies, provide a 
possible explanation of these two curves if technology were a factor in production.
8. This graph suggests what about producing strawberry pies?

10. If S1 represents the production of strawberry pies before 9/11/2001
and S2 after 9/11, what possible production factor could account for this difference?
11. If S1 represents the use of frozen strawberries and S2 the use of fresh strawberries
what conclusions can you draw as a producer of pies?
