| Change 1 |
- 3 u |
- 276 |
+ 3 u |
+ 276 |
| After 1 |
2 u |
+ 184 |
8 u |

+ 69 |
- 2 u |
- 69 |
| After 2 |
4 u |
+ 253 |
6 u |
+ 207 |
35 x 460= 276
460 - 276 = 184
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 276
=
25100 x 276
= 69
276 - 69 = 207
184 + 69 = 253
If Zara received another $190 in the end, Zara and Shannon would have the same amount of money.
6 u + 207 = 4 u + 253 + 190
6 u - 4 u = 253 + 190 - 207
2 u = 236
1 u = 236 ÷ 2 = 118
Amount that Shannon had at first
= 5 u
= 5 x 118
= $590
Answer(s): $590
