Q. 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. 40 students brought their lunch. How many students in total are in Ridgewood Junior High School?Answer:
Understand Problem: Understand the problem and identify the given information.We know that 2% of students brought their lunch and that this corresponds to 40 students. We need to find the total number of students in the school.
Set Up Equation: Set up the equation to find the total number of students.Let the total number of students be represented by T. Since 2% of T is equal to 40 students, we can write the equation as:0.02×T=40
Solve Equation: Solve the equation for T to find the total number of students.Divide both sides of the equation by 0.02 to isolate T:T=0.0240
Calculate Total: Calculate the total number of students. T=0.0240=2000
