Supply and demand are foundational concepts that illustrate the relationship between the availability of goods and services and the desire for them. When a product is in high demand and the supply is low, prices tend to rise as consumers compete to purchase the limited items. Conversely, if there is an abundance of a product and demand decreases, prices typically fall. This interaction of supply and demand helps businesses decide how much product to produce and at what price to sell it, affecting the overall economy.
