The answer is upward by exactly $3.50.
The supply curve shifts to the left, the consumer price rises, and the seller's price fall if the government raises the tax on a good.
A tax increase has no impact on the demand curve and has no effect on how elastic supply and demand are.
Given that it is a tax on top of already-imposed levies, this possible tax rise may be referred to be marginal.
Hence, a $3.50 tax per gallon of paint placed on the sellers of paint will shift the supply curve upward or leftward by exactly $3.50.
