Demand for parking in the City of Chambana is given by Q_d= 180 - 0.5P, and the supply is Q_s= P - 60, where price is in cents per car per day and quantity is in hundreds of cars parked per day.

1. Draw a graph of the given demand and supply curve and label it as D₀ and S₀.
2. Indicate numerically all relevant intercepts for your demand and supply curves on your graph.
3. Find the short run equilibrium price and quantity in this market and label the numbers you found on the graph.
