Ben and Sean had some money at first. Ben received 2 times as much money as Sean every week. At the end of 8 weeks, both of them had the same amount of money. If Sean had $1200 at first and Ben had $1840 at the end of those 8 weeks, what is the ratio of Ben's money to the total amount of money at first?

$1840 |
$1840 |
Amount that Sean received every week
= 1840 - 1200
= $640
1 u = 640
Amount that Ben received every week
= 2 u
= 2 x 640
= $1280
Amount that Ben had at first
= 1840 - 1280
= $560
Total amount that Ben and Sean had at first
= 1200 + 560
= $1760
Ben's amount : Total amount
560 : 1760
7 : 22
Answer(s): 7 : 22
