Luis |
Nick |
More |
| Before |
4 u + $66.90 |
4 u |
$66.90 |
| Change |
|
- 3 u |
|
| After |
4 u + $66.90 |
1 u |
3 u + $66.90 |
Luis had $112.20 more than Nick in the end.
4 u + 66.90 - 1 u = 112.20
3 u + 66.90 = 112.20
3 u = 112.20 - 66.90
3 u = 45.30
1 u = 45.30 ÷ 3 = 15.10
Amount that Luis had at first
= 4 u + 66.90
= 4 x 15.10 + 66.90
= 60.40 + 66.90
= $127.30
Answer(s): $127.30
