A cell phone company offers two plans for unlimited calling. The first plan has a monthly charge of $25 and 8.08 per text messag

Alja [10]

The answer is 125 messages.
Firstly the best thing to do is create two different equations.
1. y=25+.08x
2. y=20+.12x
Then you plug into Desmos and see at what point they cross. They cross at (125, 35).
Therefore for 125 text messages would cost 35$ for each plan.
