Answer:
if the price increases by 1 percent, the quantity demanded will decrease by 2 percent.
Explanation:
As we know that
Price elasticity of demand = (Percentage change in quantity demanded) รท (percentage change in price)
Since the price elasticity of demand is -2 that means the price is increased and the quantity demanded is decreased
The price would be increased by 1% and the quantity demanded would be decreased by 2% because of this, the price elasticity would be negative
