Answer 2

the
`100\%` of students in the class are
`40` students

the
`97.5\%` of students here in class today are
`39`

Explanation:

Let

x-------------> total students in the class

y------------- >number of the students here in class

so

`y=0.975x`

we know that

`x< 50`

the interval solution for x is all whole numbers belong to the interval

`[0,49]`

the solution will be a number belonging to the interval
`[0,49]` such that when multiplying by
`97.5\%` it gives me a whole number

see the attached excel table

the
`100\%` of students in the class are
`40` students

the
`97.5\%` of students here in class today are
`39`
