7-12.

Twenty-five percent of the students at Marcus Garvey Middle School bring their lunches from home. $225$ students do not bring their lunch. How many students attend the school? Draw and label a diagram to show the number and percent of each group of students.

Since $25\%$ of the students bring lunches from home, then $75\%$ of the students must not bring their lunches to school.
If $225$ is $75\%$ of the students, how many total students attend the school and how many bring lunches from home?

After finding out each value, create a diagram to illustrate this ratio.
