.
Since the ratio   is between 3 and 4, at least 4*2 = 8 Chaperones are required (are needed) for 80 students, according to the school guidelines.

    Actually, these guidelines are uncompleted:

    While they establish the rule for every 25 students, they say nothing for the number of students in the range from 1 to 24.

    From the point of view of SOLVING the given problem, this uncompletenes is FATAL, and, formally speaking, 
    does not allow to solve the problem without additional assumptions.

Ans: 80/25 = 3.2
------
There are 3.2 sets of 35 students.
# of Chaperones must be either 2*3 = 6 or 2*3+1 = 7
