Omg i have that same question on a math test
Step-by-step explanation:
He has done 70 push ups because by the 15th he has done 35 push ups add 15 more days and u get 70 .
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.
