Final answer:
When economists say that the quantity demanded for a product has increased, it means that more units of the product are being bought at a given price.
Step-by-step explanation:
When economists say that the quantity demanded for a product has increased, it means that more units of the product are being bought at a given price. The quantity demanded is the total number of units that consumers would purchase at a specific price.
An increase in quantity demanded can occur when the price of a product decreases, which makes it more attractive to buyers. This is known as the law of demand, which states that as price decreases, quantity demanded increases, and vice versa.
