Question

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?

Answer 1

Answer:

13 books

Step-by-step explanation:

The equation is already given, which makes the question more easy.

7b + 8 < 100

7b < 100 - 8

b < 92/7

b < 13.14

b(max) = 13 { b must be a whole number since it represents number of books}

Verification:

7(13) + 8 = 99 < 100
