Answer:
Price Elasticity of Demand = 3
Step-by-step explanation:
Price Elasticity of demand is degree of responsive change in quantity demanded due to change in price.
Price Elasticity of Demand :
Percentage Change in Demand / Percentage change in Price
Percentage Change in demand = 15% ; Percentage change in price = 5%
So, Price Elasticity of Demand = 15 / 5 = 3
It is greater than 1 , so the demand is elastic.
