pens - 3x
rulers - 5x
3x+5x= 24
8x=24
x=3
so she bought 9 pens and 15 rulers
amount spent on pens and rulers = 9(1.20) + 15(.80) = 22.80
money spent on files : money spent on pens&rulers = 8:3
money spent on files/22.8 = 8/3
= 60.80
rulers - 5x
3x+5x= 24
8x=24
x=3
so she bought 9 pens and 15 rulers
amount spent on pens and rulers = 9(1.20) + 15(.80) = 22.80
money spent on files : money spent on pens&rulers = 8:3
money spent on files/22.8 = 8/3
= 60.80
