(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,Cindy sells _____ pumpkins,and her producer surplus is _____.

A) four;$2
B) three;$8
C) two;$3
D) one;$5

Cindy sells three pumpkins because at the equilibrium price of $8, she is willing to sell up to three pumpkins since her costs for the first three pumpkins are below $8. Her producer surplus is the difference between what she receives ($8 per pumpkin for three pumpkins, totaling $24) and her total costs ($6 + $7 + $8 = $21), which equals $3. However, the correct calculation for her producer surplus should consider the difference between the market price and her cost for each pumpkin sold, which actually results in a surplus of $8 ($2 for the first pumpkin, $3 for the second, and $3 for the third).
