Marion and Penelope had an equal number of caramel apples. After Marion bought another 24 caramel apples and Penelope bought another 4 caramel apples, Marion had thrice as many caramel apples as Penelope. Find the number of caramel apples that each of them had at first.

Marion |
Penelope |
| Before |
3 u - 24 |
1 u - 4 |
| Change |
+ 24 |
+ 4 |
| After |
3 u |
1 u |
The number of caramel apples that Marion and Penelope had at first is the same.
3 u - 24 = 1 u - 4
3 u - 1 u = 24 - 4
2 u = 20
1 u = 20 ÷ 2 = 10
Number of caramel apples that each had at first
= 10 - 4
= 6
Answer(s): 6
