Question #76297

Answer 1

`A = B + 13`

Explanation:

We're told that `13` dollars is what Nicole earns, regardless of how many books she sells. So `13` is constant.

We are also told that `A` refers to the total amount of money Nicole earns, while `B` stands for the number of books she sells.

Given that, we can say that Nicole makes `$13` plus
`$1` for every book she sells

If we rewrite that in "math language" we get `A = 13 + 1 xx B` or just `A = B + 13`
