Answer:
The number of students that bring their lunches is 12
Step-by-step explanation:
Let
x -----> the number of students that bring their lunches
y -----> the total number of students in a class
we know that
The number of students that bring their lunches divided by the total number of students in a class must be equal to 3/8

-----> equation B
substitute the value of y in equation A and solve for x
therefore
The number of students that bring their lunches is 12
