Total amount that Barbara and Joelle had at first
= 6 u + 3 u + 33
= 9 u + 33
9 u + 33 = 258
6 u + 5 u = 258 - 33
9 u = 225
1 u = 225 ÷ 9 = 25
Amount that Barbara had at first
= 6 u
= 6 x 25
= $150
Amount that Joelle had at first
= 258 - 150
= $108
At first
Barbara : Joelle
150 : 108
25 : 18
Answer(s): 25 : 18
