Bobby and Lee had some money at first. Bobby received 3 times as much money as Lee every day. At the end of 2 days, both of them had the same amount of money. If Lee had $1350 at first and Bobby had $1620 at the end of those 2 days, what is the ratio of Bobby's money to the total amount of money at first?

$1620 |
Amount that Lee received every day
= 1620 - 1350
= $270
1 u = 270
Amount that Bobby received every day
= 3 u
= 3 x 270
= $810
Amount that Bobby had at first
= 1620 - 810
= $810
Total amount that Bobby and Lee had at first
= 1350 + 810
= $2160
Bobby's amount : Total amount
810 : 2160
3 : 8
Answer(s): 3 : 8
