Consider the following combinations of price and quantity demanded for an unnamed good. These questions ask you to perform several percentage change an elasticity calculations. When calculating percentage change, some questions ask you to use the traditional formula and some ask you to use the midpoint formula. For clarity, these two formulas are given below. The values you calculate should be between -100 and 100 (not -1 to 1). Please include the sign (if negative) in all of your responses....
