Joe has 1/3 as much money as Antwan. After Antwan gives $15 to Joe, he had 3/5 as much money as Joe. How much money did Joe have at first?

Let the amount of money that Antwan has==A

Then, Joe has ==1/3A

 

A - 15 ==3/5 * [1/3A + 15]

A - 15==1/5A + 9

A - 1/5A ==9 + 15

4/5A ==24

4A ==24 * 5 ==120

 

A ==120 / 4 ==$30 what Antwan started with

1/3 * 30 ==$10 what Joe started with
