You join an Internet service. You get the first 5 hours for free, and then you pay $2 per hour. How many hours of Internet use, h, can you get for $45?
$45 ÷ 2=22.5
22.5 + 5 free hours = 27.5 hours total.
You have to divide the amount of money you have by the $2 per hour and then you add the 5 free hours.
