Problem 4 please it builds off problem 3

Problem 3: Suppose that in the market for one-bedroom apartments in Boulder, Colorado, the demand is Q = 12,000 - 5P and the supply is Q=-4500 + 5P. (a) Calculate equilibrium price, quantity, consumer surplus, and producer surplus. (6) Show the results from (a) on the following graph. Problem 4: This problem builds on Problem 3. To support lower income residents, suppose the City of Boulder enacts a price ceiling for one-bedroom apartments. This price ceiling is capped at 75% of the equilibrium price found in Problem 3. (a) Calculate the new quantity of apartments rented and the identify the price of these apartments. (b) Is there a shortage or surplus of apartments after this policy change? Calculate the quantity of this shortage/surplus. (c) Calculate the new consumer and producer surplus. Calculate the deadweight loss, (d) Show on the following graph the new quantity sold, the new price paid, the new consumer and producer surplus, and identify the area that represents deadweight loss
