On which side of the demand and supply graph is the tax represented?

The tax is represented on the left side of the demand and supply graph because, in the context of supply and demand, taxes affect the supply curve. When a tax is imposed on a good or service, it effectively increases the cost of production for suppliers. This shift leads to a decrease in supply, which is illustrated by a leftward shift of the supply curve. The new equilibrium price will be higher for consumers, and the quantity sold will generally decrease.

The location of the tax representation being on the left emphasizes that it is the suppliers who are affected first, altering their willingness to produce and sell the product at previous price levels due to the additional cost incurred from the tax. Thus, all these considerations help in understanding where taxes fit into the overall demand and supply framework in economics.
