The law of demand states that, if all other factors remain equal, the higher the price of a good, the less people will demand that good. In other words, the higher the price, the lower the quantity demanded. The amount of a good that buyers purchase at a higher price is less because as the price of a good goes up, so does the opportunity cost of buying that good. The law of supply says that at higher prices, sellers will supply more of an economic good. From the seller’s perspective, the opportunity cost of each additional unit that they sell tends to be higher and higher.
