Ratio is 5girls:7boys with total 72 students 
5+7= 12
72➗12= 6
6(5:7)= 30 girls : 42 boys
New ratio is 3:4 with 48 boys
48➗4= 12
So for girls 3x12= 36
So started with 30 girls ended with 36 girls... 6 girls joined band during the school year.
        
                    
             
        
        
        
(x+4) + ((x-15)+4)= 41
2x-7= 41
2x= 48
x= 24
