💱 Every receipt you've ever seen has this idea inside it.
Supply and demand are two important concepts in economics. Supply refers to how much of a product or service is available, while demand is how much people want that product or service. When the supply of an item is high and the demand is low, prices usually go down. Conversely, when demand is high and supply is low, prices tend to go up. Understanding supply and demand helps us see how prices change in the market.
