| Before |
4 u + 56 |
4 u |
| Change |
- 1 u - 14 |
- 3 u |
| After |
3 u + 42 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Perry and Jen had in the end
= 3 u + 42 + 1 u
= 4 u + 42
4 u + 42 = 330
3 u + 1 u = 330 - 42
4 u = 288
1 u = 288 ÷ 4 = 72
Amount that Perry had in the end
= 3 u + 42
= 3 x 72 + 42
= 216 + 42
= $258

Amount that the Jen had in the end
= 1 u
= $72
