1 u + 25 |
2 u - 25 |

| Change 1 |
- 25 |
+ 25 |
|
| After 1 |
1 u |
2 u |
|
| Change 2 |
+ 1 u |
- 1 u |
|
| After 2 |
2 u |
1 u |
57 |
Total number of pens that Brandon and Cody had at first and in the end remains unchanged.
Total number of pens
= 2 u + 1 u
= 3 u
1 u = 57 ÷ 3 = 19
Number of pens that Brandon had at first
= 1 u + 25
= 19 + 25
= 44
