Jane and Pamela had an equal number of chocolate bars. After Jane bought another 27 chocolate bars and Pamela bought another 5 chocolate bars, Jane had thrice as many chocolate bars as Pamela. Find the number of chocolate bars that each of them had at first.

| Before |
3 u - 27 |
1 u - 5 |
| Change |
+ 27 |
+ 5 |
| After |
3 u |
1 u |
The number of chocolate bars that Jane and Pamela had at first is the same.
3 u - 27 = 1 u - 5
3 u - 1 u = 27 - 5
2 u = 22
1 u = 22 ÷ 2 = 11
Number of chocolate bars that each had at first
= 11 - 5
= 6
Answer(s): 6
