$1620 |
Amount that Jeremy received every month
= 1620 - 1140
= $480
1 u = 480
Amount that Zeph received every month
= 2 u
= 2 x 480
= $960
Amount that Zeph had at first
= 1620 - 960
= $660
Total amount that Zeph and Jeremy had at first
= 1140 + 660
= $1800
Zeph's amount : Total amount
660 : 1800
11 : 30
Answer(s): 11 : 30
