Question 381738
 A new 1,000 mile system of Comcast cable costs an average of $15,000/mile or $15 million to build. Basic cable with monthly service charges is $30 per month. 
How many homes are needed to break even?
15 million/30 = (1/2) million 
----
Comment: That is a meaningless number.  Home fees do not a single mile of 
cable service, they support many miles of cable service.
------------------------------------------------------------- 

How many homes are needed to return a 10 % profit?
Comment: Another meaningless number.
1.10*15 million = 16.5 million
---
16.5 million/30 = 0.55 million homes
