The price elasticity of demand for face mask is -0.8. what must occur to the price of face masks in order for the quantity demanded to rise by 20%?
Price elasticity = -0.8
Quantity demanded or face masks rise by 20%.
It otherwise means that the price of face masks must have been decreased.
Elasticity = % change in QD/% change in Price
-0.8 = 20%/% change in Price
% change in Price = -25%
This otherwise means the price decreased by 25%
Elasticity = % change in QD/% change in Price
Elasticity = 20%/-25% = -0.8
Price elasticity is always comes in negative because of inverse relationship between price and quantity demanded.
