Respuesta :
There are 70 people in the band. This is because 28 of 70 is 40%.
Let the total students in the band be = x
Number of students who play brass instrument = 28
This 28 is 40 percent of x
So, the number of students will be =
[tex]\frac{40x}{100}=28[/tex]
[tex]40x=2800[/tex]
[tex]x=70[/tex]
So total number of students in the band are 70.
