Nora and Abi had an equal number of caramel apples. After Nora bought another 30 caramel apples and Abi bought another 8 caramel apples, Nora had thrice as many caramel apples as Abi. Find the number of caramel apples that each of them had at first.

Nora |
Abi |
| Before |
3 u - 30 |
1 u - 8 |
| Change |
+ 30 |
+ 8 |
| After |
3 u |
1 u |
The number of caramel apples that Nora and Abi had at first is the same.
3 u - 30 = 1 u - 8
3 u - 1 u = 30 - 8
2 u = 22
1 u = 22 ÷ 2 = 11
Number of caramel apples that each had at first
= 11 - 8
= 3
Answer(s): 3
