Total |
| Before |
3 u + 74 |
7 u + 58 |
102 |
| Change |
- 74 |
- 58 |
|
| After |
3 u |
7 u |
|
Amount that Lee had spent
= 74 - 16
= $58
Total amount that Liam and Lee had at first
= 3 u + 74 + 7 u + 58
= 10 u + 132
10 u + 132 = 102
10 u = 102 - 132
10 u = -30
1 u = -30 ÷ 10 = -3
Amount that Liam had at first
= 7 u + 74
= 7 x -3 + 74
= -21 + 74
= $53
Answer(s): $53
