| Before |
4 u + 80 |
4 u |
| Change |
- 1 u - 20 |
- 3 u |
| After |
3 u + 60 |
1 u |
25% =

75100 =
34Total amount that Mark and Hazel had in the end
= 3 u + 60 + 1 u
= 4 u + 60
4 u + 60 = 228
3 u + 1 u = 228 - 60
4 u = 168
1 u = 168 ÷ 4 = 42
Amount that Mark had in the end
= 3 u + 60
= 3 x 42 + 60
= 126 + 60
= $186
