| Before |
4 u + 60 |
4 u |
| Change |
- 1 u - 15 |
- 3 u |
| After |
3 u + 45 |
1 u |
25% =

14 75% =
75100 =
34Total amount that Neave and Betty had in the end
= 3 u + 45 + 1 u
= 4 u + 45
4 u + 45 = 381
3 u + 1 u = 381 - 45
4 u = 336
1 u = 336 ÷ 4 = 84
Amount that Neave had in the end
= 3 u + 45
= 3 x 84 + 45
= 252 + 45
= $297
