Answer:
A. What is Sprint Corporations's break-even number of accounts, using the data and assumption given?
B. How much revenue per account would be sufficient for Sprint Corporation to break even, if the number of accounts remained constant?
Explanation:
break even number of accounts = (total fixed costs / contribution margin) x total number of accounts
break even number of accounts = ($18,233.2 millions / $20,478.2 millions) x 60 million subscribers = 53.42 million
revenue per account = (53.42 million / 60 million) x ($33,347 / 60) = $494.83 per account
