In economics, quantity supplied represents the number of goods or services that a supplier produces and sells at a given market price. Supply is different from the actual supply (that is, total supply). This is because price changes affect how much suppliers actually put into the market.
A quantity supplied is the quantity of a product that a retailer intends to sell at a specific price, called the delivery quantity. A time period is also usually specified when describing shipping quantities. Example: If the price of an orange is 65 cents, he has a supply of 300 per week.
