if a cell phone provider offers a plan that costs $20 per month plus $0.10 text messages sent or received a comparable plan costs $50 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

You would have to send 300 text messages

Step-by-step explanation:

1. Turn problem into 20 + 0.10x = 50

2. Subtract 20 from both sides to get 0.10x = 30
