Supply and demand is perhaps one of the most fundamental concepts of economics and it is the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer.
The law of supply and demand is an economic theory that explains how supply and demand are related to each other and how the relationship affects the price of goods and services. It's a basic economic principle that states that when there is an oversupply of a good or service, prices fall.
