Step-by-step explanation:
The term that describes the relationship between an item desired and a potential purchaser is demand. Demand refers to how much quantity of a product or service is desired by buyers. It is the amount of a product that people are willing to buy at a certain price and is influenced by factors such as price, availability, and consumer preferences.
For example, if a student wants to buy a popular video game, the demand for that game would be high. But if the price of the game increases significantly, the demand may decrease as fewer people are willing to buy it at the higher price.
Understanding demand is important for businesses as it helps them determine the price, supply, and marketing strategies for their products or services.
