Let x be the total number of students in Ridgewood Junior High School.

We are given that 25% of students brought their lunch, which is 0.25x students. We are also given that 50 students brought their lunch.

So we can write the equation:

0.25x = 50

Solving for x:

x = 50 / 0.25
x = 200

There are a total of 200 students in Ridgewood Junior High School.
