we know that
**The school paid a unit price ($) per book of **
350 1 , 137.50 ​ = 3.25
$ 3.25 per book.
In order to make a profit of $1,500, the agenda books need to be
sold for a minimum of
3.25 + 350 1500 ​ = 3.25 + 4.29 = 7.54
$ 7.54 per book.
Check
$ 7.54 ∗ 350 brings revenue of
$ 2 , 639 ,
and ( 2 , 639 − 1 , 137.50 ) gives profit of
$ 1 , 501.50
therefore
the answer is
$** 7.54 per book. **

The least amount Lizzie's school can charge for each agenda book is $7.54. This price includes the cost of the books purchased and the desired profit of $1,500. Selling at this price ensures the school covers its costs and achieves its profit goal.
