| Before |
4 u + 72 |
4 u |
| Change |
- 1 u - 18 |
- 3 u |
| After |
3 u + 54 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Charlie and Hilda had in the end
= 3 u + 54 + 1 u
= 4 u + 54
4 u + 54 = 398
3 u + 1 u = 398 - 54
4 u = 344
1 u = 344 ÷ 4 = 86
Amount that Charlie had in the end
= 3 u + 54
= 3 x 86 + 54
= 258 + 54
= $312

Amount that the Hilda had in the end
= 1 u
= $86
