Answer: The elasticity of demand will determine the degree to which quantity demanded rises.
Step-by-step explanation:
Acc. to the law of demand, demand for a normal good is negatively related to its price. When price of the good falls, quantity demanded rises.
Price elasticity of demand shows us the magnitude of change in quantity demanded to a change in the price of the good.
So, when price falls, elasticity will show us by the degree to which quantity demanded rises.
