Based on the estimates of Ghose and Han (2014), the demand function for mobile applications at Apple's App Store is \(Q_{A}=1.4 p^{-2}\) and the demand function at Google Play is \(1.4 p^{-3.7}\), where the quantity is in millions of apps. What is the total demand function for apps? If the price for an app is \(\$ 1\), what is the equilibrium quantity demanded by Apple customers, Google customers, and all customers?
