| Before |
4 u + 40 |
4 u |
| Change |
- 1 u - 10 |
- 3 u |
| After |
3 u + 30 |

75100 =
34Total amount that Gabriel and Lynn had in the end
= 3 u + 30 + 1 u
= 4 u + 30
4 u + 30 = 278
3 u + 1 u = 278 - 30
4 u = 248
1 u = 248 ÷ 4 = 62
Amount that Gabriel had in the end
= 3 u + 30
= 3 x 62 + 30
= 186 + 30
= $216

Amount that the Lynn had in the end
= 1 u
= $62
