_feedback_correct: : Demand elasticity measures the responsiveness of quantity to price. It is represented in terms of “percentage changes,” which is written as “%∆”. _feedback_incorrect: : Demand elasticity measures the responsiveness of quantity to price.

The percentage change formula is 100% * (new value – original value) / original value. Here, we calculate %∆Q =100% * (2,212,000 - 2,541,000)/2,541,000
