demand curve

A demand curve is a graph that shows how much of a product people want to buy at different prices. Typically, as the price goes up, the quantity people are willing to buy goes down, and vice versa. This relationship suggests that lower prices encourage more purchases, while higher prices limit them. The curve helps businesses understand how changing prices might affect sales and revenue. It's based on the idea that consumer interest varies with price, influenced by factors like preferences, income, and availability.
