Answer:
law of supply and demand
Explanation:
As the price of a good or service increases, the consumers will be less willing to purchase the good or service, therefore the quantity demanded will decrease. When the price of a good or service increases, this results in a higher opportunity cost for the consumer and a lower consumer surplus.
Inversely, when the price of the good or service increases, the suppliers will be more willing to produce the good or service, therefore the quantity supplied will increase.
