| Before |
3 u + 78 |
8 u + 66 |
188 |
| Change |
- 78 |
- 66 |

| After |
3 u |
8 u |

Amount that Luke had spent
= 78 - 12
= $66
Total amount that Zeph and Luke had at first
= 3 u + 78 + 8 u + 66
= 11 u + 144
11 u + 144 = 188
11 u = 188 - 144
11 u = 44
1 u = 44 ÷ 11 = 4
Amount that Zeph had at first
= 8 u + 78
= 8 x 4 + 78
= 32 + 78
= $110
Answer(s): $110
