Answer: 125 minutes to make tests for five classes, $2388 in two months, and 4800 women to 3,600 men
1 class: 25 minutes
5 classes: [tex]25[/tex] × [tex]5[/tex] [tex]= 125[/tex] minutes
[tex]\frac{3582}{3}=\frac{x}{2}[/tex]
[tex]\frac{7164}{3}=\frac{3x}{3}[/tex]
[tex]2,388 = x[/tex]
[tex]x= 2,388[/tex]
[tex]\frac{8}{6}=\frac{x}{3600}[/tex]
[tex]\frac{28,800}{6} =\frac{6x}{6}[/tex]
[tex]4,800=x[/tex]
[tex]x=4,800[/tex]
