| Change 1 |
- $15 |
+ $15 |

| Change 2 |
+ $36 |
- $36 |

| After |
1 u + $18 |
1 u |
$200 |
Total amount that Ryan and Brandon had
= 1 u + 1 u + $18
= 2 u + 18
2 u + 18 = 200
2 u = 200 - 18
2 u = 182
1 u = 182 ÷ 2 = 91
Amount that Ryan had in the end
= 1 u + 18
= 91 + 18
= $109
Amount that Ryan had at first
= 109 - 36 + 15
= $88
Answer(s): $88
