| |
Pierre |
Zeph |
| Before |
1 u + 30 |
3 u + 8 |
| Change |
- 30 |
- 8 |
| After |
1 u |
3 u |
Pierre and Zeph had an equal number of caramel apples at first.
3 u + 8 = 1 u + 30
3 u - 1 u = 30 - 8
2 u = 22
1 u = 22 ÷ 2 = 11
Number of caramel apples that each of them had at first
= 1 u + 30
= 11 + 30
= 41
Answer(s): 41
