| Before |
2 u + 80 |
9 u + 68 |
115 |
| Change |
- 80 |
- 68 |

| After |
2 u |
9 u |

Amount that Archie had spent
= 80 - 12
= $68
Total amount that Henry and Archie had at first
= 2 u + 80 + 9 u + 68
= 11 u + 148
11 u + 148 = 115
11 u = 115 - 148
11 u = -33
1 u = -33 ÷ 11 = -3
Amount that Henry had at first
= 9 u + 80
= 9 x -3 + 80
= -27 + 80
= $53
Answer(s): $53
