$1710 |
Amount that Jack received every week
= 1710 - 1140
= $570
1 u = 570
Amount that Seth received every week
= 2 u
= 2 x 570
= $1140
Amount that Seth had at first
= 1710 - 1140
= $570
Total amount that Seth and Jack had at first
= 1140 + 570
= $1710
Seth's amount : Total amount
570 : 1710
1 : 3
Answer(s): 1 : 3
