Understanding the importance of demand and supply is crucial in the world of economics. Demand refers to the quantity of a product or service that consumers are willing to buy at a given price, while supply refers to the quantity of a product or service that producers are willing to offer at a given price. The equilibrium between demand and supply determines the market price of goods and services. Changes in demand and supply can lead to price fluctuations, shortages, or surpluses in the market. Businesses use the concepts of demand and supply to make pricing decisions, forecast sales, and manage inventory levels effectively.
