Explanation:
Price elasticity of demand is a term on economics which measures the change in the quantity demanded of a particular good or service in relation to its price change. It is used to determine the changes in demand due to changes in price and to understand how the real economy works.
Expressed mathematically, price elasticity of demand is:
Price elasticity of demand= % change in quantity demanded / % change in price
Price elasticity of demand= -3.8 / 10 =-0.38
Therefore, the price elasticity if demand is -0.38.
