Demand is said to be when the quantity demanded is very responsive to changes in price.

Demand is said to be price elastic.

Explanation:

If the percentage change in quantity demanded is greater than the percentage change in price, demand is said to be price elastic , or very responsive to price changes.

The price elasticity of demand or supply will differ among goods. For example, consider a 50 percent increase in the price of two goods—candy bars and prescription medicines. While the demand for both candy bars and prescription medicines should decline in response to the price increases, the percentage change in the quantity demanded of candy bars is likely to be much greater than the percentage change in the quantity demanded of prescription medicines because candy bars are less of a necessity than prescription medicines.
