Jack and Asher had some money at first. Jack received 2 times as much money as Asher every day. At the end of 4 days, both of them had the same amount of money. If Asher had $1320 at first and Jack had $1800 at the end of those 4 days, what is the ratio of Jack's money to the total amount of money at first?

$1800 |
Amount that Asher received every day
= 1800 - 1320
= $480
1 u = 480
Amount that Jack received every day
= 2 u
= 2 x 480
= $960
Amount that Jack had at first
= 1800 - 960
= $840
Total amount that Jack and Asher had at first
= 1320 + 840
= $2160
Jack's amount : Total amount
840 : 2160
7 : 18
Answer(s): 7 : 18
