| Before |
2 u + 77 |
7 u + 61 |
183 |
| Change |
- 77 |
- 61 |

| After |
2 u |
7 u |

Amount that Peter had spent
= 77 - 16
= $61
Total amount that Ahmad and Peter had at first
= 2 u + 77 + 7 u + 61
= 9 u + 138
9 u + 138 = 183
9 u = 183 - 138
9 u = 45
1 u = 45 ÷ 9 = 5
Amount that Ahmad had at first
= 7 u + 77
= 7 x 5 + 77
= 35 + 77
= $112
Answer(s): $112
