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

You need to include the original coordinates of the triangle to answer this. and how much does it translate (move left right up down)
