Final answer:
The law of demand illustrates that a higher price for a good leads to a lower quantity demanded, and a lower price leads to a higher quantity demanded, assuming all other factors are held constant.
Step-by-step explanation:
The law of demand states that there is an inverse relationship between the price of a good or service and the quantity demanded. This principle is fundamental to understanding how markets operate. To summarize, the key aspects of the law of demand are as follows:
- As the price of a good increases, the quantity demanded will decrease, holding all other factors constant.
- As the price of a good decreases, the quantity demanded will increase, holding all other factors constant.
This means that if the price of a gallon of gasoline rises, people will generally buy less gasoline, perhaps by carpooling or using other forms of transportation—provided that other factors influencing demand do not change.
