$179 |
| Change 1 |
- $16 |
+ $16 |
|
| Change 2 |
+ $22 |
- $22 |
|
| After |
1 u + $19 |
1 u |
$179 |
Total amount that Xavier and Elijah had
= 1 u + 1 u + $19
= 2 u + 19
2 u + 19 = 179
2 u = 179 - 19
2 u = 160
1 u = 160 ÷ 2 = 80
Amount that Xavier had in the end
= 1 u + 19
= 80 + 19
= $99
Amount that Xavier had at first
= 99 - 22 + 16
= $93
Answer(s): $93
