$123 |
| Change 1 |
- $13 |
+ $13 |
|
| Change 2 |
+ $38 |
- $38 |
|
| After |
1 u + $37 |
1 u |
$123 |
Total amount that Daniel and Ian had
= 1 u + 1 u + $37
= 2 u + 37
2 u + 37 = 123
2 u = 123 - 37
2 u = 86
1 u = 86 ÷ 2 = 43
Amount that Daniel had in the end
= 1 u + 37
= 43 + 37
= $80
Amount that Daniel had at first
= 80 - 38 + 13
= $55
Answer(s): $55
