Unformatted text preview: . Adding to both sides of the equation gives 3 = 300. Dividing both sides by 3 gives = 100. Plugging = 100 back into either equation for quantity demanded or supplied gives Q = 200. b. Now P is the price received by sellers and P + T is the price paid by buyers. Equating quantity demanded to quantity supplied gives 2P = 300 - ( + ). Adding to both sides of the equation gives 3 = 300 . Dividing both sides by 3 gives = 100 /3. This is the price received by sellers. The buyers pay a price equal to the price received by sellers plus the tax ( + = 100 + 2 /3). The quantity sold is now = 2 = 200 2 /3. c. Because tax revenue is equal to x and = 200 2 /3, tax revenue equals 200- 2 2 /3. Figure 3 shows a graph of this relationship. Tax revenue is zero at = 0 and at = 300. Figure 3 2...
