Suppose that a tax of T is placed on buyers, so the new demand equation is; QD=300-(P+T).?

Question

Solve for the new equilibrium. What happens to the price recieved by sellers, the price paid by buyers, and quantity sold?

Answer 1

Equilibrium can be find only if there are also Supply equation given, so give Qs=.... and we can find equilibrium. To find "New" equilibrium you need to specify old one, so old equations also should be given.
