Total amount that Sabrina and Dana had at first
= 5 u + 3 u + 84
= 8 u + 84
8 u + 84 = 660
5 u + 4 u = 660 - 84
8 u = 576
1 u = 576 ÷ 8 = 72
Amount that Sabrina had at first
= 5 u
= 5 x 72
= $360
Amount that Dana had at first
= 660 - 360
= $300
At first
Sabrina : Dana
360 : 300
6 : 5
Answer(s): 6 : 5
