Twenty-five percent of 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.

To solve, since 25% bring their lunch we can assume 75% do not bring their lunch from school.

225 is the 75% so to solve we do an equation as such:
x(.75) = 225

x = 225/.75
x = 300

Therefore there are 300 students at the school

You can use a double bar graph to draw the diagram, using the left y axis as percent, and the right y axis as number

Now we have 25% of 300 who bring their lunches which equals 75 students
