Consider a demand curve with the following equation Q = 300 -4P a) What is the point-to-point elasticity of demand between the (Q,P) moving from the point (60,60) to the point (100,50)? b) What is the point-to-point elasticity of demand between the (Q,P) moving from the point (100,50) to the point (60, 60)? c) What is the point-to-point elasticity of demand between the (Q,P) between the point (60,60) and the point (100, 50) using the midpoint method? d) What is the point elasticity of demand at the point (100,50) (i.e. using calculus)
