| Before |
7 u + $37.80 |
7 u |
$37.80 |
| Change |
|
- 3 u |
|
| After |
7 u + $37.80 |
4 u |
3 u + $37.80 |
Jeremy had $44.10 more than Ryan in the end.
7 u + 37.80 - 4 u = 44.10
3 u + 37.80 = 44.10
3 u = 44.10 - 37.80
3 u = 6.30
1 u = 6.30 ÷ 3 = 2.10
Amount that Jeremy had at first
= 7 u + 37.80
= 7 x 2.10 + 37.80
= 14.70 + 37.80
= $52.50
Answer(s): $52.50
