Total |
| Before |
3 u + 71 |
5 u + 41 |
184 |
| Change |
- 71 |
- 41 |
|
| After |
3 u |
5 u |
|
Amount that Luis had spent
= 71 - 30
= $41
Total amount that Luke and Luis had at first
= 3 u + 71 + 5 u + 41
= 8 u + 112
8 u + 112 = 184
8 u = 184 - 112
8 u = 72
1 u = 72 ÷ 8 = 9
Amount that Luke had at first
= 5 u + 71
= 5 x 9 + 71
= 45 + 71
= $116
Answer(s): $116
