Suppose that a market is described by the following supply and demand equations: Qs = 4P; Qd = 100－P; a. Solve for the equilibrium price and the equilibrium quantity. b. Suppose that a tax of $5 is placed on buyers, so the new demand equation is Qd = 100 – (P + 5). Solve for the new equilibrium. What happens to the price received by sellers, the price paid by buyers, and the quantity sold? c. Calculate the deadweight loss from tax.
