Explanation:
Demand is a term that is born out of the human desires , wants or needs.
Demand can be defined or referred to as the amount a consumer is able and willing to pay in other to purchase goods and services that they desire or want.
The Law of demand states that the Quantity of goods and services demanded is inversely proportional to the prices of these goods and services.
