A supply curve is a graphical representation of how much of a product or service a producer is willing and able to offer at different prices. It demonstrates the relationship between price and quantity supplied, with higher prices usually linked to higher quantities supplied. In other words, it shows the maximum amount sellers are willing to sell before prices become too costly. By understanding the supply curve, businesses can make better-informed decisions about pricing, product availability, and more. Put simply, the supply curve is a valuable tool that helps producers maximize profits while still meeting customer demands.
