| Before |
4 u + 52 |
4 u |
| Change |
- 1 u - 13 |
- 3 u |
| After |
3 u + 39 |
1 u |
25% =

75100 =
34Total amount that Warren and Zoe had in the end
= 3 u + 39 + 1 u
= 4 u + 39
4 u + 39 = 387
3 u + 1 u = 387 - 39
4 u = 348
1 u = 348 ÷ 4 = 87
Amount that Warren had in the end
= 3 u + 39
= 3 x 87 + 39
= 261 + 39
= $300
