A cell phone provider offers a plan that costs ​$40 per month plus ​$0.10 per text message sent or received. A comparable plan costs ​$60 per month but offers unlimited text messaging. How many text messages would have to be sent or received in order for the plans to cost the same each​ month?

Answer:

200 messages

Explanation:

Let m = number of messages.

Plan A: 0.1m + 40

Plan B: 60

0.1m + 40 = 60

0.1m = 20

m = 20/0.1

m = 200

Answer: 200 messages
