Question #72947

If the supply equation is given as Q=-200+10P, the price elasticity of supply between R40 and R50, calculated using the arc elasticity of demand, is?

Expert's answer

Arc elasticity of demand is ((Q2 – Q1)/midpoint Q)/((P2 – P1)/midpoint P)

Q1=-200+10P = 40, P=24

Q2=-200+10P = 50, P=25

Arc elasticity of demand = ((50-40)/45)/((25-24)/24,5)=5.44

Q1=-200+10P = 40, P=24

Q2=-200+10P = 50, P=25

Arc elasticity of demand = ((50-40)/45)/((25-24)/24,5)=5.44
