Total |
| Before |
1 u + 11 |
2 u - 11 |
84 |
| Change 1 |
- 11 |
+ 11 |
|
| After 1 |
1 u |
2 u |
|
| Change 2 |
+ 1 u |
- 1 u |
|
| After 2 |
2 u |
1 u |
84 |
Total number of markers that Caden and Peter had at first and in the end remains unchanged.
Total number of markers
= 2 u + 1 u
= 3 u
1 u = 84 ÷ 3 = 28
Number of markers that Caden had at first
= 1 u + 11
= 28 + 11
= 39
Answer(s): 39
