Question

1. 40% of the students in a class like apples for breakfast. if 20 students like apples, how many students are in the class?

o a. 50
o b. 30
o c. 40
o d. 60

Explanation:

Step1: Define the variable

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

Step2: Set up the equation

We know that \( 40\% \) of \( x \) is equal to 20 (the number of students who like apples). So we can write the equation as \( 0.4x = 20 \).

Step3: Solve for \( x \)

To find \( x \), we divide both sides of the equation by \( 0.4 \): \( x=\frac{20}{0.4} \). Calculating this, \( \frac{20}{0.4} = 50 \).

Answer:

A. 50
