| |
Harry |
Gabriel |
| Before |
1 u + 24 |
4 u + 3 |
| Change |
- 24 |
- 3 |
| After |
1 u |
4 u |
Harry and Gabriel had an equal number of chocolate bars at first.
4 u + 3 = 1 u + 24
4 u - 1 u = 24 - 3
3 u = 21
1 u = 21 ÷ 3 = 7
Number of chocolate bars that each of them had at first
= 1 u + 24
= 7 + 24
= 31
Answer(s): 31
