Final answer:
To find the total number of students in Ridgewood Junior High School, set up an equation using the given information and solve for 'x'.
Step-by-step explanation:
To find the total number of students in Ridgewood Junior High School, we need to determine the number of students who brought their lunch and then use that information to find the total number of students.
- Step 1: Let's assume that the total number of students in the school is 'x'.
- Step 2: We are given that 10% of the students brought their lunch, which is equivalent to 0.1x. We can set up an equation: 0.1x = 41 (since 41 students brought their lunch).
- Step 3: Solve the equation by dividing both sides by 0.1 to isolate 'x': x = 41 / 0.1 = 410.
Therefore, there are 410 students in total in Ridgewood Junior High School.
