| Before |
4 u + 76 |
4 u |
| Change |
- 1 u - 19 |
- 3 u |
| After |
3 u + 57 |
1 u |
25% =

75100 =
34Total amount that Bryan and Opal had in the end
= 3 u + 57 + 1 u
= 4 u + 57
4 u + 57 = 261
3 u + 1 u = 261 - 57
4 u = 204
1 u = 204 ÷ 4 = 51
Amount that Bryan had in the end
= 3 u + 57
= 3 x 51 + 57
= 153 + 57
= $210
