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
Times each by two it looks like. Then just write the answer in scientific notation.
N equals negative 22 the work is above
