Perry and Julian had some money at first. Perry received 2 times as much money as Julian every week. At the end of 2 weeks, both of them had the same amount of money. If Julian had $1120 at first and Perry had $2170 at the end of those 2 weeks, what is the ratio of Perry's money to the total amount of money at first?

$2170 |
Amount that Julian received every week
= 2170 - 1120
= $1050
1 u = 1050
Amount that Perry received every week
= 2 u
= 2 x 1050
= $2100
Amount that Perry had at first
= 2170 - 2100
= $70
Total amount that Perry and Julian had at first
= 1120 + 70
= $1190
Perry's amount : Total amount
70 : 1190
1 : 17
Answer(s): 1 : 17
