Total amount that Sarah and Nicole had at first
= 5 u + 4 u + 58
= 9 u + 58
9 u + 58 = 841
5 u + 4 u = 841 - 58
9 u = 783
1 u = 783 ÷ 9 = 87
Amount that Sarah had at first
= 5 u
= 5 x 87
= $435
Amount that Nicole had at first
= 841 - 435
= $406
At first
Sarah : Nicole
435 : 406
15 : 14
Answer(s): 15 : 14
