Question

23. Naphtall's cell phone company charges $0.25 per text plus a $10 flat fee. Asher's cell phone company charges $0.10 per text plus a $25 flat fee. At how many texts are Naphtali and Asher paying exactly the same amount?​

Answer 1

Well the equations should look like 0.25x+10 and 0.1x+10; mx+b formula
At that point I suggest making a graph and graphing for the answer.





Answer is 100
