After 2 |

+ 133 |
4 u |
+ 152 |
23 x 285= 190
285 - 190 = 95
20% x 5 u
=
20100 x 5 u
= 1 u
20% x 190
=
20100 x 190
= 38
190 - 38 = 152
95 + 38 = 133
If Elyse received another $193 in the end, Elyse and Rachel would have the same amount of money.
4 u + 152 = 2 u + 133 + 193
4 u - 2 u = 133 + 193 - 152
2 u = 174
1 u = 174 ÷ 2 = 87
Amount that Rachel had at first
= 3 u
= 3 x 87
= $261
Answer(s): $261
