| Change 1 |
- $14 |
+ $14 |

| Change 2 |
+ $31 |
- $31 |

| After |
1 u + $28 |
1 u |
$118 |
Total amount that Justin and Liam had
= 1 u + 1 u + $28
= 2 u + 28
2 u + 28 = 118
2 u = 118 - 28
2 u = 90
1 u = 90 ÷ 2 = 45
Amount that Justin had in the end
= 1 u + 28
= 45 + 28
= $73
Amount that Justin had at first
= 73 - 31 + 14
= $56
Answer(s): $56
