Answer 1

There is a total of 720 students are in Ridgewood Junior High School.

5% of students brought their lunch.

36 students brought their lunch.

5% of students brought their lunch and equal to 36

so 5% of x = 36

5/100 * x = 36

x = 36*100/5

x = 36*20

x = 720

There is a total of 720 students are in Ridgewood Junior High School.
