| Change 1 |
- $18 |
+ $18 |
|
| Change 2 |
+ $35 |
- $35 |
|
| After |
1 u + $10 |
1 u |
$164 |
Total amount that Peter and Wesley had
= 1 u + 1 u + $10
= 2 u + 10
2 u + 10 = 164
2 u = 164 - 10
2 u = 154
1 u = 154 ÷ 2 = 77
Amount that Peter had in the end
= 1 u + 10
= 77 + 10
= $87
Amount that Peter had at first
= 87 - 35 + 18
= $70
Answer(s): $70
