Question

Sandy is upgrading her internet service. Fast internet charges $15 for installation and $53.45 per month. Quick internet has free installation but charges $55.95 per month

The equation is ____=_____+_____

Answer 1

15 + 53.45x = 55.95x

Explanation:

We want to know in how many months BOTH COSTS WOULD BE SAME. So we EQUATE the expressions for both. This equation can be solved for x to find the number of months for which the internet service would cost the same.
