Verified step by step guidance
1
Understand that the law of demand describes the relationship between the price of a good and the quantity demanded by consumers.
Recall that the law of demand states: "All else held constant, as the price of a good increases, the quantity demanded decreases," and conversely, as the price decreases, the quantity demanded increases.
Identify that this relationship is inverse, meaning price and quantity demanded move in opposite directions.
Recognize that the other statements either confuse demand with supply or incorrectly describe the relationship between price and quantity demanded.
Conclude that the correct explanation of the law of demand is: "As the price of a good increases, the quantity demanded decreases, all else held constant."
