sandy is upgrading her internet service . Fast internet charges $60 for installation and $50.45 per month. Quick internet has free installation but charges $57.95 per months. write an equation that can be used to find the number of months at which the internet service would cost the same and solve the equation.

Let's let x equal the number of months that payment is made. $60 is constant, because it is only charged once. Let's let y equal the total cost for x amount of months. For fast internet: y=50.45x+60 For quick internet: y=57.95x The equations will equal each other when the payment has reached the same amount. 50.45x+60=57.95x
