Generally, producers would o?er more of a product for sale as the price increases because they can make more money and higher profits; and to o?er less of the product at lower prices. This is based on the assumption that a producer’s aim is to make as much profit as possible, i.e. to maximize profits. So the amount of a product supplied will increase as the price rises; and if the price drops then less of the product will be supplied. This is the principle of the law of supply. The law of supply - the amount of a product supplied
will increase as the price rises; and if the price drops then less of the product will be supplied
