Explanation:

Price elasticity of demand is the measure of how quantity demanded for a good or service changes as a result of changes in price. Price elasticity of demand is calculated by dividing the percentage change in quantity demanded by the percentage change in price. If the result is equal or greater than one (1) the good or service is elastic. If the result is lower than one (1), the product is inelastic.
