Answer:

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

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

Step-by-step 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
