Answer:

0

Step-by-step explanation:

The reason the answer would be 0 is because there is 20 students in all

This equation tells us that 14 students ate pizza and 6 ate burgers

Therefore we would add 14 + 6 to see how many students that is

In this case that is 20 students

If there is only 20 students in the lunchroom then you couldn't add anymore students

So, your answer is 0 students brought lunch from home

Hope this helps!
