What is the formula for the price elasticity of demand?
Percent change in quantity demanded/ percentage change in price
The point method measure the price elasticity of demand for specific change in the product’s price. What is the formula?
%Q= Quantity demanded after the change - quantity demanded before the change/ quantity demanded before the change. %P = Price after the change - price before the change/price before the change. %E = %Q/QP
What s the midpoint method (arc Method) formula for elasticity of demand?
%E= ((Q1-Q2)/(Qz+Q2))/((P1-p2)/(P1+P2))
How do you evaluate the elasticity of demand?
Greater than = relatively elastic
Equal to one - unitary elastic
Less than one = Relatively inelastic
Infinite = perfectly elastic
What is the formula for elasticity of supply?
%E= Percentage change in quantity supplies/percentage change in price
