Total amount that Winnie and Sarah had at first
= 5 u + 4 u + 39
= 9 u + 39
9 u + 39 = 273
5 u + 4 u = 273 - 39
9 u = 234
1 u = 234 ÷ 9 = 26
Amount that Winnie had at first
= 5 u
= 5 x 26
= $130
Amount that Sarah had at first
= 273 - 130
= $143
At first
Winnie : Sarah
130 : 143
10 : 11
Answer(s): 10 : 11
