Explanation:
You make the equation. If she can put 12 on each page then you would multiply 12 by p (pages) and have it equal to 152
152=12p
To solve this, you would divide 12 from both sides
152/12=12.666
Therefore, 12.6=pages but since there aren’t 12.6 pages and you need to keep it a whole number you would round up to 13 because if you kept it at twelve pages you would have those pictures left over.
