Respuesta :
First find the percentage of students who didn't like reading mystery stories.(100-85=15)
If 15% =30students
85%=?
85/15*30=170
Therefore 170 students liked reading mystery stories
If 15% =30students
85%=?
85/15*30=170
Therefore 170 students liked reading mystery stories
you would take the 30 multiply it by 15. then, take the product and multiply it by .85 and that is your answer. So, 382.5
