Question

Enter an inequality that represents the description, and then solve.

Toni can carry up to 22 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 3 lb, and her
books (b) weigh 3 lb each. How many books can she carry in her backpack?
The inequality is
Toni can carry up to
books in her backpack.

Answer 1

Tony’s backpack can carry weight up to 22 but not more that that
If the variable n represents the total weight carried by tony
Then ; n less than or equal to (n=1+3+3b
=4+3b
Where b represents book
4+3b is less or equal to 22
3b is less or equal to 18
b is less or equal to 6

Therefore Tony’s backpack cannot carry more than 6 books
