Question

Mr. Harrison has $416 to spend on supplies for his classroom. He will buy a bookshelf and some books. The bookshelf costs $80. He will buy books that cost $4 each. Write, then solve an inequality to find the number of books (b), at most, that Mr. Harrison can buy.

Answer 1

So we take his before cost $416

then we subtract the bookshelf due to we are given that

so after subtracting $416 and $80 we get our next part to work with.

we get 356.

we then are given that each book costs $4 each.

we take $356 and divide it by $4.

4/356= 81.8 total of books

but it we can't have 1/8  a book so round up to 82 books.

Answer 2

A) 416=80+4x

B) 416=80+4x

    336=4x

    84=x

Mr. Harrison can buy a maximum of 84 books for his new bookshelf.
