Jenson and Luke had some money at first. Jenson received 3 times as much money as Luke every week. At the end of 6 weeks, both of them had the same amount of money. If Luke had $1380 at first and Jenson had $1860 at the end of those 6 weeks, what is the ratio of Jenson's money to the total amount of money at first?

$1860 |
Amount that Luke received every week
= 1860 - 1380
= $480
1 u = 480
Amount that Jenson received every week
= 3 u
= 3 x 480
= $1440
Amount that Jenson had at first
= 1860 - 1440
= $420
Total amount that Jenson and Luke had at first
= 1380 + 420
= $1800
Jenson's amount : Total amount
420 : 1800
7 : 30
Answer(s): 7 : 30
