Cody and Zeph had some money at first. Cody received 2 times as much money as Zeph every month. At the end of 2 months, both of them had the same amount of money. If Zeph had $1480 at first and Cody had $1850 at the end of those 2 months, what is the ratio of Cody's money to the total amount of money at first?

$1850 |
Amount that Zeph received every month
= 1850 - 1480
= $370
1 u = 370
Amount that Cody received every month
= 2 u
= 2 x 370
= $740
Amount that Cody had at first
= 1850 - 740
= $1110
Total amount that Cody and Zeph had at first
= 1480 + 1110
= $2590
Cody's amount : Total amount
1110 : 2590
3 : 7
Answer(s): 3 : 7
