Charlie and Eric had some money at first. Charlie received 3 times as much money as Eric every day. At the end of 8 days, both of them had the same amount of money. If Eric had $1210 at first and Charlie had $1650 at the end of those 8 days, what is the ratio of Charlie's money to the total amount of money at first?

$1650 |
Amount that Eric received every day
= 1650 - 1210
= $440
1 u = 440
Amount that Charlie received every day
= 3 u
= 3 x 440
= $1320
Amount that Charlie had at first
= 1650 - 1320
= $330
Total amount that Charlie and Eric had at first
= 1210 + 330
= $1540
Charlie's amount : Total amount
330 : 1540
3 : 14
Answer(s): 3 : 14
