she will have
left.
so she should sell
band posters.
60

63; 42; 18

Step-by-step explanation:

The ratio 90:60= 1.5

If we set up the equation to we can cross multiply and have 90x=3780 Then we would divide 3780 by 90 to leave x by itself and x=42.

Once we have x we can substitute it in the ratio and check our answer by making sure that 63 divided by 42= 1.5.

We need to have a total of 42 band posters and we have 60 which means we need to sell 18 band posters.
