Valen and Tommy had some money at first. Valen received 3 times as much money as Tommy every week. At the end of 2 weeks, both of them had the same amount of money. If Tommy had $1330 at first and Valen had $1710 at the end of those 2 weeks, what is the ratio of Valen's money to the total amount of money at first?

$1710 |
Amount that Tommy received every week
= 1710 - 1330
= $380
1 u = 380
Amount that Valen received every week
= 3 u
= 3 x 380
= $1140
Amount that Valen had at first
= 1710 - 1140
= $570
Total amount that Valen and Tommy had at first
= 1330 + 570
= $1900
Valen's amount : Total amount
570 : 1900
3 : 10
Answer(s): 3 : 10
