Gabriel and Andy had some money at first. Gabriel received 4 times as much money as Andy every week. At the end of 4 weeks, both of them had the same amount of money. If Andy had $1320 at first and Gabriel had $1700 at the end of those 4 weeks, what is the ratio of Gabriel's money to the total amount of money at first?

$1700 |
Amount that Andy received every week
= 1700 - 1320
= $380
1 u = 380
Amount that Gabriel received every week
= 4 u
= 4 x 380
= $1520
Amount that Gabriel had at first
= 1700 - 1520
= $180
Total amount that Gabriel and Andy had at first
= 1320 + 180
= $1500
Gabriel's amount : Total amount
180 : 1500
3 : 25
Answer(s): 3 : 25
