Document Summary

It is important to notice two things about this concept. (quantity demand) Second, quantity demanded refers to a slow of purchases. The total amount of some product that consumers in the relevant market want to buy in a given time period is influenced by the following important variables: A basic economic hypothesis is that the price of a product and the quantity demanded are related negatively, other things being equal. That is, the lower the price, the higher the quantity demanded; the higher the price, the lower the quantity demanded. Demand schedule: a table showing the relationship between quantity demanded and the price of a commodity, other things being equal. Demand curve: represents the relationship between quantity demanded and price, other things being equal. Substitutes two goods are considered substitutes if they satisfy similar needs or desires, such as butter and margarine. Gasoline and bicycles are not directly related commodities.
