Egypt has the demand and supply functions for product X;

P=2+3.Q^s

P=56-6.Q^D

P shows 1000 USD per tonnes of product X and Q shows quantity demanded and supplied in tonnes.

Product X is freely traded in world market at P=14(000) per tonne. Egyptian government allows for free trade at first but then adds a tariff of 3(000) USD.

Question: What is the total welfare after the tariff in terms of USD? There is nothing missing here.
