Reuben had 4 times as much money as Steven at first. After spending some money, Reuben realized that Steven had three times as much as he had. If Steven had $18, how much did Reuben spend?

Hello Guest!

 

\(s=18\\ r=4\cdot 18\\ r=72\\ 18=3\cdot (r-x)\\ 18=3\cdot (72-x)\\ 18=216-3x\\ -198=-3x\\ \color{blue}x=66\)

Reuben spent $ 60.
