A cell phone provider offers a plan that costs ​$30 per month plus ​$0.10 per text message sent or received. A comparable plan costs ​$50 per month but offers unlimited text messaging. Complete parts a. and b. below.

Accepted Solution

A:
To solve this we need to create equations with x being text messages

30 + .10x = 50

So .10x = 20

20/.1 = 200

The answer is 200 text messages
