(Table: Pumpkin Market) There are two consumers,Andy and Ben,in the market for pumpkins.Their willingness to pay for each pumpkin is shown in the table Pumpkin Market.There are two producers of pumpkins,Cindy and Diane,and their costs are also shown.The equilibrium price for pumpkins is $8 and the equilibrium quantity is 5.At the equilibrium price and quantity,Diane sells _____ pumpkins,and her producer surplus is _____.

A) four;$11
B) three;$8
C) two;$6
D) one;$4

At the price $8, Cindy will be willing to supply 4 pumpkins and Diane will be willing to supply 2 pumpkins. Therefore, at the equilibrium quantity of 5, Cindy sells 3 pumpkins and Diane sells 2 pumpkins. Diane's producer surplus is the difference between the price and her cost, which is ($8 - $2) * 2 = $12. However, she only sells 2 pumpkins so her producer surplus is $12/2 = $6 per pumpkin. Therefore, the answer is choice C, two pumpkins and producer surplus of $6.
