The problem is asking you to see which phone plan is better, Verizon or AT&T. It's was along which phone service is better when you text more or text less. The answer that I got was if you send less than 550 texts that Verizon is better. But if you text more than 550 texts that AT&T is better.
The plan that I made was to start writing an equation. So it said that for Verizon they charged an activation fee of $70, but they charges .10 cents per text. So that's how I got my Verizon equation. For AT&T they charged .20 cents per text but an activation fee of $15. So that's how I got my equation for AT&T phone service.
After I made my equations I went to desmos.com on my phone and typed in both of my equations and it plotted both lines. Then
