Brandon |
Archie |
More |
| Before |
8 u + $30.90 |
8 u |
$30.90 |
| Change |
|
- 3 u |
|
| After |
8 u + $30.90 |
5 u |
3 u + $30.90 |
Brandon had $42.30 more than Archie in the end.
8 u + 30.90 - 5 u = 42.30
3 u + 30.90 = 42.30
3 u = 42.30 - 30.90
3 u = 11.40
1 u = 11.40 ÷ 3 = 3.80
Amount that Brandon had at first
= 8 u + 30.90
= 8 x 3.80 + 30.90
= 30.40 + 30.90
= $61.30
Answer(s): $61.30
