Leo and Ryan together have $48. Ryan owns 2/3 of the amount. Leo remembered that Ryan owed him $10 but he also owed Ryan $7. After the debts had been settled, how much money does Leo have?
Thoughts? Step-by-step reasoning:
Ryan owns $48 x 2 / 3 = $32 of the $48. While Leo owns $48 - $32 = $16 of the $48. Leo had $16 + $10 = $26 after Ryan paid him $10. But since he owed Ryan $7, then Leo has $26 - $7 = $19.
Thus, the answer is 19.
