|
Daniel |
Henry |
Before |
1 u + 23 |
3 u + 7 |
Change |
- 23 |
- 7 |
After |
1 u |
3 u |
Daniel and Henry had an equal number of caramel apples at first.
3 u + 7 = 1 u + 23
3 u - 1 u = 23 - 7
2 u = 16
1 u = 16 ÷ 2 = 8
Number of caramel apples that each of them had at first
= 1 u + 23
= 8 + 23
= 31
Answer(s): 31
