- How much did Charlie have left in the end?
- Express the amount of money Min had left as a fraction of the amount of money Charlie had in the end. (Give your answer in the simplest form)

| Before |
10 u + 95 |
10 u |
| Change |
- 2 u - 19 |
- 7 u |
| After |
8 u + 76 |
3 u |

210 70% =
70100 =
710Total amount that Charlie and Min had in the end
= 8 u + 76 + 3 u
= 11 u + 76
11 u + 76 = 274
8 u + 3 u = 274 - 76
11 u = 198
1 u = 198 ÷ 11 = 18
Amount that Charlie had in the end
= 8 u + 76
= 8 x 18 + 76
= 144 + 76
= $220
(b)
Amount that the Min had in the end
= 1 u
= $18
