Brian is ordering books online. He has $100 to spend on the books. Each book costs $7. The shipping charge for the entire order is $8. The number of books, b, that Brian can buy is represented by the inequality 7b + 8 < 100. How many books can Brian buy without overspending?
You have $100 but the shipping is $8 so you subtract that from $100 and get $92, At $7 dollers a book you can get 13 books before going over 7x13=91. So the answer is 13 and you will spend $99 total.
