Question

Suppose that the price of basketball tickets at your college is determined by market forces. Currently, the demand and supply schedules are as follows:

Price	Quantity Demanded	Quantity Supplied
(Dollars)	(Tickets)	(Tickets)
4	10,000	8,000
8	8,000	8,000
12	6,000	8,000
16	4,000	8,000
20	2,000	8,000

Use the blue points (circle symbol) to graph the demand for basketball tickets. Then use the orange points (square symbol) to graph the supply of tickets. Finally, use the black point (plus symbol) to indicate the equilibrium price and quantity in this market.

Your college plans to increase total enrollment next year by 5,000 students. The additional students will have the following demand schedule:

Price	Quantity Demanded
(Dollars)	(Tickets)
4	4,000
8	3,000
12	2,000
16	1,000
20	0

Add the old demand schedule and the demand schedule for the new students to calculate the new demand schedule for the entire college. Use the purple points (diamond symbol) to draw this new demand curve on the previous graph. Then use the grey point (star symbol) to indicate the new equilibrium price and quantity.
