35 x 220= 132
220 - 132 = 88
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 132
=
25100 x 132
= 33
132 - 33 = 99
88 + 33 = 121
If Roshel received another $168 in the end, Roshel and Julie would have the same amount of money.
6 u + 99 = 4 u + 121 + 168
6 u - 4 u = 121 + 168 - 99
2 u = 190
1 u = 190 ÷ 2 = 95
Amount that Julie had at first
= 5 u
= 5 x 95
= $475
Answer(s): $475
