3 u |
Total amount that Joelle and Dana had at first
= 6 u + 3 u + 48
= 9 u + 48
9 u + 48 = 624
6 u + 5 u = 624 - 48
9 u = 576
1 u = 576 ÷ 9 = 64
Amount that Joelle had at first
= 6 u
= 6 x 64
= $384
Amount that Dana had at first
= 624 - 384
= $240
At first
Joelle : Dana
384 : 240
8 : 5
Answer(s): 8 : 5
