PLEASE HELP! DUE IN 2 MINS

MR.harrison has $416 to spend on supplies for his classroom. He will buy a bookshelf and some books. The bookshelf cost $80. He will buy books that cost $4 each. Write then slove an inequality to find the number of B (B) at most he can buy

Answer 1

You already know the total will be 416, and that the bookshelf costs $80, so you already have a part of the equation. The rest of the equation can be 4b, where b is equal to books. So, you'd write it like this:
4b+80=416

To solve this, you have to move 80 to the other side. To do this, subtract 80 from both sides so that you get this:
4b=336

Then, divide both sides by 4 to get the maximum amount of books Mr. Harrison can buy:
b=84

Mr. Harrison can buy a maximum of 84 books, along with the $80 bookshelf.
