Answer:
480
Step-by-step explanation:
We can set up a proportion:
#students that eat carrots / #students surveyed=#students that eat carrots / #students surveyed
x will equal the number of students in Sarah's school who eat carrots.
30/50 = x/800
We can simplify
3/5=x/800
We cross multiply
5x=3*800
5x=2400
x=480
Hope this helps!
