Question

Verizon wireless offers an Internet plan for $20 a month plus a $20 set up fee. Consolidated Communications offers an Internet plan for $25 a month plus a $10 set up fee. After how many months will the plans be equal

Answer 1

After the second month, because for the first equation, y = 20x + 20 if you replace x with 2, you get y = 60, and if you replace 2 for the second equation, y = 25x + 10 you get y = 60.
