Jeremiah and Michael had an equal number of caramel apples at first. After Jeremiah bought another 10 caramel apples and Michael lost 20 caramel apples, Jeremiah had four times as many caramel apples as Michael. Find the number of caramel apples each of them had at first.

| Before |
4 u - 10 |
1 u + 20 |
| Change |
+ 10 |
- 20 |
| After |
4 u |
1 u |
The number of caramel apples that Jeremiah and Michael at first is the same.
4 u - 10 = 1 u + 20
4 u - 1 u = 20 + 10
3 u = 30
1 u = 30 ÷ 3 = 10
Number of caramel apples that each of them had at first
= 1 u + 20
= 10 + 20
= 30
Answer(s): 30
