A monopolist sells the same product at the same price into two different markets. The demand for the product in market #1 is denoted D1(p) = 30 – 2p where p is the unit price. The demand for the product in market #2 is given by D2(p) = 80 – 3p. Explain why the elasticity of total demand is not defined at a unit price of $15.
