Suppose that the market demand function for ice cream (IC) is given by Qd_IC= 12000-2000P_IC and the market supply function for ice cream is given by Qs_IC= 2000P_IC where Q = ice cream cones per week, P is the price (in dollars) of one ice cream cone.

1. Find the equilibrium price and the equilibrium quantity.
2. Find the market demand and supply schedules of ice cream when P = $0,1,2,3,4,5,6.
3. Graph, on one set of axes, the market demand and supply curves for ice cream and show the equilibrium point.
