$1680 |
Amount that Bobby received every week
= 1680 - 1440
= $240
1 u = 240
Amount that Jenson received every week
= 2 u
= 2 x 240
= $480
Amount that Jenson had at first
= 1680 - 480
= $1200
Total amount that Jenson and Bobby had at first
= 1440 + 1200
= $2640
Jenson's amount : Total amount
1200 : 2640
5 : 11
Answer(s): 5 : 11
