| Change 1 |
- 3 u |
- 120 |
+ 3 u |

| After 2 |
4 u |
+ 110 |
6 u |
+ 90 |
35 x 200= 120
200 - 120 = 80
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 120
=
25100 x 120
= 30
120 - 30 = 90
80 + 30 = 110
If Marion received another $204 in the end, Marion and Min would have the same amount of money.
6 u + 90 = 4 u + 110 + 204
6 u - 4 u = 110 + 204 - 90
2 u = 224
1 u = 224 ÷ 2 = 112
Amount that Marion had at first
= 5 u + 200
= 5 x 112 + 200
= 560 + 200
= $760
Answer(s): $760
