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

substitute the value of y in equation A and solve for x
therefore
The number of students that bring their lunches is 12
400,000+90,000+2,000+0+30+02=492,032 is the answer put that and you will get a good grade :)
