As we can see on the demand graph, there is an inverse relationship between price and quantity demanded. Economists call this the Law of Demand. If the price goes up, the quantity demanded goes down (but demand itself stays the same). If the price decreases, quantity demanded increases.

How does quantity effect price?

If there is a decrease in supply of goods and services while demand remains the same, prices tend to rise to a higher equilibrium price and a lower quantity of goods and services. ... However, when demand increases and supply remains the same, the higher demand leads to a higher equilibrium price and vice versa.

How does demand increase affect 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.
