Question

all students in ridgewood junior high school either got their lunch in the school cafeteria or brought it from home on tuesday. 2% of students brought their lunch. 39 students brought their lunch. how many students in total are in ridgewood junior high school?

Explanation:

Step1: Define the variable

Let \( x \) be the total number of students in the school.

Step2: Set up the equation

We know that 2% of the total students is equal to 39 (the number of students who brought lunch). So we can write the equation as \( 0.02x = 39 \).

Step3: Solve for \( x \)

To find \( x \), we divide both sides of the equation by 0.02: \( x=\frac{39}{0.02} \). Calculating this, we get \( x = 1950 \).

Answer:

The total number of students in Ridgewood Junior High School is 1950.
