Answer:
20
Step-by-step explanation:
Given:
Lisa is checking out at the bookstore.
Each book (b) costs $1.50 and she has a $5 off coupon she can use.
She wants to spend $25 or less in the bookstore.
Solve:
Since there is a $5 off coupon..
$1.5b - $5.00<=$25.00
$1.5b<= $30.00
$1.5b/1.5 = $30.00/1.5
b=20
Lisa can buy 20 book.
