After 8 months of internet use both the connection will cost the same.
Step-by-step explanation:
Fast Internet charges $40 for installation and $52.45 per month.
So, the total cost after using x months of the internet in Fast Internet will be
C = 40 + 52.45x
Quick Internet has free installation but charges $57.45 per month.
So, the total cost after using x months of the internet in Quick Internet will be
C = 57.45x
Now, if those two cost are same then
40 + 52.45x = 57.45x
⇒ 5x = 40
⇒ x = 8
Therefore, after 8 months of internet use both the connection will cost the same. (Answer)
