| Change 1 |
- 2 u |
- 320 |
+ 2 u |

| After 2 |
2 u |
+ 224 |
4 u |
+ 256 |
23 x 480= 320
480 - 320 = 160
20% x 5 u
=
20100 x 5 u
= 1 u
20% x 320
=
20100 x 320
= 64
320 - 64 = 256
160 + 64 = 224
If Jaslyn received another $196 in the end, Jaslyn and Roshel would have the same amount of money.
4 u + 256 = 2 u + 224 + 196
4 u - 2 u = 224 + 196 - 256
2 u = 164
1 u = 164 ÷ 2 = 82
Amount that Roshel had at first
= 3 u
= 3 x 82
= $246
Answer(s): $246
