Expert Solution
Step 1: Define Elasticity of demand

Elasticity of demand is a measure of the responsiveness of the quantity demanded of a good or service to changes in its price or other determinants, such as income or the prices of related goods. Specifically, it measures the percentage change in the quantity demanded resulting from a 1% change in the price of the good, holding all other factors constant.
