Billy and Simon had some money at first. Billy received 2 times as much money as Simon every week. At the end of 8 weeks, both of them had the same amount of money. If Simon had $1040 at first and Billy had $2040 at the end of those 8 weeks, what is the ratio of Billy's money to the total amount of money at first?

$2040 |
$2040 |
Amount that Simon received every week
= 2040 - 1040
= $1000
1 u = 1000
Amount that Billy received every week
= 2 u
= 2 x 1000
= $2000
Amount that Billy had at first
= 2040 - 2000
= $40
Total amount that Billy and Simon had at first
= 1040 + 40
= $1080
Billy's amount : Total amount
40 : 1080
1 : 27
Answer(s): 1 : 27
