Answer:

Inequality:
$3b+1+2\leq 18$

Toni can carry up to 5 books.

Explanation:

"Up to" means you cannot exceed over the amount, meaning everything in her backpack has to be less than or equal to 18 lbs.

Add 1 and 2, to get 3 and subtract from both sides, which gets you
$3b\leq 15$

Finally, divide both sides by 3, which gets you 5.
