What is the 'Law Of Demand'

The law of demand is a microeconomic law that states, all other factors being equal, as the price of a good or service increases, consumer demand for the good or service will decrease, and vice versa. The law of demand says that the higher the price, the lower the quantity demanded, because consumers’ opportunity cost to acquire that good or service increases, and they must make more tradeoffs to acquire the more expensive product

The law of demand states that, all other things being equal, the quantity bought of a good or service is a function of price. As long as nothing else changes, people will buy less of something when its price rises. They'll buy more when its price falls.
