1)Discuss the impact of the introduction of a price floor on the equilibrium price and quantity, also mentioning if there is any excess supply or demand.

2)Given that supply is given by P=2Q and demand is given by P=45-Q. Find the equilibrium price and quantity before and after a price floor of $40 is implemented

3)With the price control implemented, calculate the total consumer surplus, total producer surplus and deadweight loss (if any).

Hi, I can't figure out these questions. Can you please explain how to get to the answer? Thanks.
