    chaperones will be needed.

    Step-by-step explanation:

    1 to 25 students require (at least) 2 chaperones.

    51 to 75 students require (at least) 6 chaperones.

    This is an example of use of the ceiling function.

    The ceiling of a value  

    x

    (sometimes written as  

    ⌈

    x

    ⌉

    ) is defined as the smallest integer greater than or equal to  

    x

    .

    In the given example we are asked for

    XXX

    2

    ×

    ⌈

    53

    25

    ⌉

    XXXXXXXXX

    which is  

    6
