Understand the concept of a free market where prices and quantities are determined by the interaction of supply and demand without external controls.
Recall that the supply curve shows the relationship between price and quantity supplied by producers, while the demand curve shows the relationship between price and quantity demanded by consumers.
Identify the equilibrium point where the supply curve and demand curve intersect; this point determines the equilibrium price and equilibrium quantity.
Recognize that the equilibrium price is the price at which the quantity of the good consumers want to buy equals the quantity producers want to sell.
Note that other options like income distribution, number of firms, or government-mandated prices are not directly determined by the free market interaction of supply and demand.
