How does the law of demand help buyers to make wise decisions?

The law of demand states that if all other factors remain equal, the higher the price of a good, the fewer people will demand that good. ... 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.
