| After 2 |

4 u |
+ 136 |
23 x 255= 170
255 - 170 = 85
20% x 5 u
=
20100 x 5 u
= 1 u
20% x 170
=
20100 x 170
= 34
170 - 34 = 136
85 + 34 = 119
If Kimberly received another $205 in the end, Kimberly and Jade would have the same amount of money.
4 u + 136 = 2 u + 119 + 205
4 u - 2 u = 119 + 205 - 136
2 u = 188
1 u = 188 ÷ 2 = 94
Amount that Jade had at first
= 3 u
= 3 x 94
= $282
Answer(s): $282
