Supply

A basic economic concept that refers to the total amount of a particular commodity or service that is made available to consumers. If depicted on a graph, supply can refer to the amount available at a single price or the amount available throughout a range of prices. This is directly related to the demand for an item or service at a particular price; assuming that all factors are equal, the supply offered by manufacturers will increase, if the price rises, because all businesses aim to maximize profits. When markets become saturated and there's an excess of supply, or a decrease in demand, prices will start to drop. Supply and demand are the dominating forces of market economy.
