Quizplus · Accepted Answer

The total surplus with the tax can be calculated by adding the consumer surplus and producer surplus with the tax revenue. The consumer surplus after the tax is [1/2 x (P0-P2)x Q2], the producer surplus after the tax is [(P2-P8)x Q2], and the tax revenue is [1/2 x (P8-0)x Q2]. Adding them up gives the total surplus as [1/2 x (P0-P2)x Q2] +[(P2-P8)x Q2] + [1/2 x (P8-0)x Q2].
