In a country called The Gambia, the equation of the domestic demand curve for wheat is, QD = 200 -2P, where QD represents the domestic quantity of Wheat demanded, in tons, and P represents the price of a ton of Wheat. For The Gambia equation of the domestic supply curve for Wheat is, 60 + 3P, where QS represents the domestic quantity of Wheat supplied, in tons, and again P represents the price of a ton of wheat. If the Gambia prohibits international trade in wheat, then the equilibrium price of a ton of wheat is $52and quantity is 96 tons.
