Gavin and Emily had an equal number of chocolate bars at first. After Gavin bought another 16 chocolate bars and Emily lost 14 chocolate bars, Gavin had four times as many chocolate bars as Emily. Find the number of chocolate bars each of them had at first.

Emily |
| Before |
4 u - 16 |
1 u + 14 |
| Change |
+ 16 |
- 14 |
| After |
4 u |
1 u |
The number of chocolate bars that Gavin and Emily at first is the same.
4 u - 16 = 1 u + 14
4 u - 1 u = 14 + 16
3 u = 30
1 u = 30 ÷ 3 = 10
Number of chocolate bars that each of them had at first
= 1 u + 14
= 10 + 14
= 24
Answer(s): 24
