| After 2 |

6 u |
+ 72 |
35 x 160= 96
160 - 96 = 64
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 96
=
25100 x 96
= 24
96 - 24 = 72
64 + 24 = 88
If Gillian received another $118 in the end, Gillian and Rachel would have the same amount of money.
6 u + 72 = 4 u + 88 + 118
6 u - 4 u = 88 + 118 - 72
2 u = 134
1 u = 134 ÷ 2 = 67
Amount that Rachel had at first
= 5 u
= 5 x 67
= $335
Answer(s): $335
