Apple is contemplating raising the price of the Apple Music "Individual" Plan. Before doing so, Apple would like to estimate the effects of a price increase on the number of subscriptions sold. Suppose that Apple has enlisted your help with this task. 1. Using concepts from class, discuss three methods to estimate the effect of a price increase on the number of subscriptions sold. 2. Weighing the costs and benefits of the three approaches, which one would you recommend for Apple? Why? [Note: There is no 'right' or 'wrong' answer. We want to evaluate your reasoning based on the economic concepts learned in class.]
