T-Mobile Fought Sprint — Customers Declared The Winner
In an effort to capture market share of the wireless mobile phone network in USA, Sprint and T-Mobile have pursued extremely aggressive phone plan pricing. Both companies are offering unlimited talk, text and data for the customers, who are further encouraged to group up and form family plans to benefit from further cost savings.
For T-Mobile customers, the first line costs $70, adding the second line costs an additional $30, and any lines after that cost an additional $10 each.
For Sprint customers, the first line costs $50, adding the second line costs an additional $40, adding the third line costs an additional $30 and any lines after that cost an additional $20 each.

According to the picture, T-Mobile has prices(in $ ) = 7 0 , 3 0 , 1 0 , 1 0 , . . . . for 1st line, 2nd line, 3rd line, 4th line and so on respectively while Sprint has prices(in $ ) = 5 0 , 4 0 , 3 0 , 2 0 , . . . . for 1st line, 2nd line, 3rd line, 4th line and so on. If we take 4 lines, then we have the total cost for purchasing a family plan with 4 lines as follows ----
For T-Mobile users = $ ( 7 0 + 3 0 + 1 0 + 1 0 ) = $ 1 2 0
For Sprint users = $ ( 5 0 + 4 0 + 3 0 + 2 0 ) = $ 1 4 0 .
So, clearly we can see that T-Mobile has the cheapest plan.
