Answer:
The consumers' sensitivity to a price change.
Explanation:
The price elasticity of demand is a measure of the change in the quantity demanded by customers for a product, relative to change in price. It is computed using the following formula:
Price Elasticity of Demand = %change in quantity demanded/%change in price
If the quantity demanded for a good rises or falls proportionally more than the change in price, the good is classified as elastic. For example, if the price of salt rises by 15%, and the quantity demanded falls by 20%, then salt is an elastic good.
If the quantity demanded for a good rises or falls proportionally less than the change in price, the good is classified as inelastic. For example, if the price of gasoline rises by 30%, but the quantity demanded only falls by 10% (as it's often the case in reality), then gasoline is an inelastic good.
