3. Answer the following questions with demand and supply analysis. Draw a graph to illustrate your answer and briefly explain in words.

a) If the city council passes an ordinance requiring all apartment owners in a particularly congested area to provide one off-street parking place for each apartment that they rent out, what effect would you predict on the level of rents in that area and on the number of apartment units being rented?

b) If the city council did not require provision of parking spaces, but simply prohibited all on-street parking on the streets in this congested area, what effect would you predict on the level of rents in the area and on the number of apartment units being rented?
