Explanation:

Demand is an economic principle referring to a consumer's desire to purchase goods and services and willingness to pay a price for a specific good or service. Holding all other factors constant, an increase in the price of a good or service will decrease the quantity demanded, and vice versa

The price and quantity of goods and services in the marketplace are largely determined by consumer demand and the amount that suppliers are willing to supply. Demand and supply can be plotted as curves, and the two curves meet at the equilibrium price and quantity.

Supply and demand is an economic model of price determination in a market. ... If demand increases and supply remains unchanged, then it leads to higher equilibrium price and higher quantity. If demand decreases and supply remains unchanged, then it leads to lower equilibrium price and lower quantity.
