Supply and demand is perhaps one of the most fundamental concepts of economics and it is the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer.
As the demand curve shifts the change in the equilibrium price and quantity will be in the same direction, i.e., both will increase. If the supply curve shifts left, say due to an increase in the price of the resources used to make the product, there is a lower quantity supplied at each price.
