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
