| Before |
4 u + 80 |
7 u + 37 |
139 |
| Change |
- 80 |
- 37 |
|
| After |
4 u |
7 u |

Amount that Sam had spent
= 80 - 43
= $37
Total amount that Sean and Sam had at first
= 4 u + 80 + 7 u + 37
= 11 u + 117
11 u + 117 = 139
11 u = 139 - 117
11 u = 22
1 u = 22 ÷ 11 = 2
Amount that Sean had at first
= 7 u + 80
= 7 x 2 + 80
= 14 + 80
= $94
Answer(s): $94
