05. Consider a demand curve for chocolate given by Q=150P'2. (Notice that this can be rewritten as: Ln Q= Ln(150)-2Ln(P)). a) Compute the own price elasticity of demand and show that this demand curve is iso-elastic, that is, it exhibits a constant elasticity of demand. What would happen to revenue if the rm decreases it price? Why? b) Using an example, show that the measure of elasticity is independent of the units that you use to measure price or quantity whereas the rate of change ( AQ/AP) does depend on the units of measure
