| Before |
10 u + 85 |

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

210 70% =
70100 =
710Total amount that Julian and Gabby had in the end
= 8 u + 68 + 3 u
= 11 u + 68
11 u + 68 = 222
8 u + 3 u = 222 - 68
11 u = 154
1 u = 154 ÷ 11 = 14
Amount that Julian had in the end
= 8 u + 68
= 8 x 14 + 68
= 112 + 68
= $180
