| Before |
4 u + 96 |
4 u |
| Change |
- 1 u - 24 |
- 3 u |
| After |
3 u + 72 |
1 u |
25% =

75100 =
34Total amount that Luis and Jade had in the end
= 3 u + 72 + 1 u
= 4 u + 72
4 u + 72 = 216
3 u + 1 u = 216 - 72
4 u = 144
1 u = 144 ÷ 4 = 36
Amount that Luis had in the end
= 3 u + 72
= 3 x 36 + 72
= 108 + 72
= $180
(b)
Amount that the Jade had in the end
