Tommy and Claire had an equal number of chocolate bars at first. After Tommy bought another 17 chocolate bars and Claire lost 27 chocolate bars, Tommy had thrice as many chocolate bars as Claire. Find the number of chocolate bars each of them had at first.

Tommy |
Claire |
| Before |
3 u - 17 |
1 u + 27 |
| Change |
+ 17 |
- 27 |
| After |
3 u |
1 u |
The number of chocolate bars that Tommy and Claire at first is the same.
3 u - 17 = 1 u + 27
3 u - 1 u = 27 + 17
2 u = 44
1 u = 44 ÷ 2 = 22
Number of chocolate bars that each of them had at first
= 1 u + 27
= 22 + 27
= 49
Answer(s): 49
