27 of the amount Seth had left. How much did Seth have at first?

Total |
| Before |
2 u + 60 |
7 u + 31 |
145 |
| Change |
- 60 |
- 31 |
|
| After |
2 u |
7 u |
|
Amount that Carl had spent
= 60 - 29
= $31
Total amount that Seth and Carl had at first
= 2 u + 60 + 7 u + 31
= 9 u + 91
9 u + 91 = 145
9 u = 145 - 91
9 u = 54
1 u = 54 ÷ 9 = 6
Amount that Seth had at first
= 7 u + 60
= 7 x 6 + 60
= 42 + 60
= $102
Answer(s): $102
