Sean and Caden had some money at first. Sean received 2 times as much money as Caden every month. At the end of 6 months, both of them had the same amount of money.

$2220 |
Amount that Caden received every month
= 2220 - 1320
= $900
1 u = 900
Amount that Sean received every month
= 2 u
= 2 x 900
= $1800
Amount that Sean had at first
= 2220 - 1800
= $420
Total amount that Sean and Caden had at first
= 1320 + 420
= $1740
Sean's amount : Total amount
420 : 1740
7 : 29
Answer(s): 7 : 29
