Fill in the order form to get the price

The demand curve for salted codfish is D(P) = 200 − 5P and the supply curve S(P)=5P.

a) Draw the demand and supply curves for salted codfish and compute the equilibrium price

and quantity.

b) A quantity tax of $2 per unit sold is placed on salted codfish. Draw the new supply curve,

where the price on the vertical axis remains the price per unit paid by demanders. What

would be the new equilibrium price paid by the demanders, the new price received by the

suppliers and the quantity sold?

c) What is the loss in the consumer surplus, in the producer surplus and the deadweight loss

of the tax?
