| After 2 |

+ 143 |
6 u |
+ 117 |
35 x 260= 156
260 - 156 = 104
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 156
=
25100 x 156
= 39
156 - 39 = 117
104 + 39 = 143
If Tiffany received another $256 in the end, Tiffany and Shiyun would have the same amount of money.
6 u + 117 = 4 u + 143 + 256
6 u - 4 u = 143 + 256 - 117
2 u = 282
1 u = 282 ÷ 2 = 141
Amount that Shiyun had at first
= 5 u
= 5 x 141
= $705
Answer(s): $705
