When price decreases by 10% and quantity demanded increases by 20%, the product is considered elastic due to the greater proportional change in quantity demanded compared to the price change.
Elastic. Goods that are price elastic have substitutes available, and the percentage change in quantity demanded will decrease more than the percentage increase in price (|Ed|>1).
For example, if a 10% price decrease leads to a 20% quantity demanded increase, the elasticity value would be -20%/10% = -2, indicating elastic demand.
