Kyle and Steve together earned $24. Kyle's share was 7 times as big as Steve's share. If Kyle spends $11 at the store, how much money will Kyle have left?
Kyle : Steve = 7:1 so there are 7+ 1 = 8 'shares' each share is then 24/8 = 3 dollars
so kyle has 7 shares = 21 dollars then spends 11 dollars leaving 10 dollars.
