Suppоse the initiаl equilibrium cоrrespоnded to а quаntity equal to 1,000 and a price equal to $100. For the change in supply and no change in demand, the equilibrium quantity is 1,250 and the equilibrium price is $70. For the change in demand and no change in supply, the equilibrium quantity is 750. When both supply and demand change, assume the equilibrium is $40. Considering the changes in the diagram, use the mid points formula to determine the price elasticity of demand if the market represents lower production costs but no change in demand. Enter your answer using one decimal place. Do not enter units.
