Answer:
72% of students chose burritos
Step-by-step explanation:
first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14
then you would take that number and subtract it from the total of all students: 50-14=36

turn that into a percent and you'd get 72%
