A. 6 chaperones

B. 40 chaperones

C. 3 chaperones

D. 7 chaperones

Answer 1

We are given that the ratio of chaperon to student is at least 2 chaperon per 25 students. In this case, the number of chaperons of 80 students is 2 chaperon per 25 students * (80 students) equal to 6.4 chaperons .Since only natural numbers are allowed, then the answer should be D.7 chaperons 

Answer 2
