kohl's sells casual shirts for $9 and polo shirts for $18. total sales were $1080, and customers bought 4 times as any casual as polo shirts. how many casual shirts did kohl's sell?
there are two equations you will need in order to solve this question: [tex]9x+18y=1080
[/tex] [tex]x=4y[/tex] When you substitute 4y for x in the top equation, that should give you 20
