Look at the tables below, which show, respectively, the willingness to pay and willingness to accept of buyers and sellers of individual bags of oranges. For the following questions, assume that the equilibrium price and quantity will depend on the indicated changes in supply and demand. Assume that the only market participants are those listed by name in the two tables.

Instructions: Enter your answers as whole numbers.
a. Given the equilibrium price of $10, what is the equilibrium quantity given the data above?
Q* = bag(s).
b. What if, instead of bags of oranges, the data in the two tables dealt with a public good like fireworks displays? If all the buyers free ride, what will be the quantity supplied by private sellers?
Q* =.

P* = $.
What is the new equilibrium quantity?
Q* = bag(s).
If the new equilibrium quantity is the optimal quantity, by how many bags were oranges being overproduced before?
