Understanding the Answer

Let's break down why this is correct

Answer

The price elasticity of demand is calculated by dividing the percentage change in quantity demanded by the percentage change in price. In this case, the quantity demanded fell by 15 % when the price rose by 10 %, giving an elasticity of –1. 5. Because the absolute value of this elasticity is greater than 1, the demand is considered elastic. This means that consumers are quite responsive to price changes, so a price increase will lead to a proportionally larger drop in sales.

Detailed Explanation

When the price rises by 10% and the quantity sold falls by 15%, the drop in quantity is larger than the price rise. Other options are incorrect because The idea that demand is not sensitive to price is a misconception; Unit elastic means the percentage change in quantity equals the percentage change in price.
