the total number of student is 100
the suspended student is 14
let coach suspended x % student that is equal to 14
then
[tex]\begin{gathered} 100\times\frac{x}{100}=14 \\ x=14 \end{gathered}[/tex]so coach suspended 14% student.
[tex]40\times\frac{x}{100}=96[/tex]the value of x will give you the total number of student,
