Answer: 480

Step-by-step explanation:

We can create a ratio for this!

We have:

\frac{number of hamburgers}{total students}= \frac{new number of hamburgers}{new number of students}

We can use substitution to input the information we already know:

\frac{12}{30} = \frac{x}{1200}

Using cross multiplication, we get:

1 200(12) = 30x

14,400 = 30x

\frac{14,400}{30}=\frac{30x}{30}

x = 480

Hope this helps! :)
