In a perfectly competitive market, the equilibrium price is determined by the intersection of the supply and demand curves. At this price, the quantity supplied equals the quantity demanded, and there is no surplus or shortage of goods or services.Changes in either supply or demand can shift the equilibrium point and lead to changes in price and quantity. For example, an increase in demand for a particular product will lead to a higher equilibrium price and a larger quantity of the product being produced and sold. Conversely, a decrease in supply will lead to a higher equilibrium price and a smaller quantity being produced and sold.Supply and demand also play a crucial role in resource allocation. In a
