| Before |
10 u + 85 |

| Change |
- 2 u - 17 |
- 7 u |
| After |
8 u + 68 |

710Total amount that Neave and Abi had in the end
= 8 u + 68 + 3 u
= 11 u + 68
11 u + 68 = 244
8 u + 3 u = 244 - 68
11 u = 176
1 u = 176 ÷ 11 = 16
Amount that Neave had in the end
= 8 u + 68
= 8 x 16 + 68
= 128 + 68
= $196
