Let
x-------------> total students in the class
y------------- >97.5% of the students here in class
y=0.975*x
we know that
x< 50
the interval solution for x is ------------ > (0,50)
the solution will be a number belonging to the interval (0,50) such that when multiplying by 97.5% it gives me a whole number
see the attached excel table
the answer is
the 100% of students in the class are 40 students (X)
the 97.5 % of students here in class today are 39 (Y)
