Emily and Layla had an equal number of caramel apples at first. After Emily bought another 3 caramel apples and Layla lost 15 caramel apples, Emily had four times as many caramel apples as Layla. Find the number of caramel apples each of them had at first.

| Before |
4 u - 3 |
1 u + 15 |
| Change |
+ 3 |
- 15 |
| After |
4 u |
1 u |
The number of caramel apples that Emily and Layla at first is the same.
4 u - 3 = 1 u + 15
4 u - 1 u = 15 + 3
3 u = 18
1 u = 18 ÷ 3 = 6
Number of caramel apples that each of them had at first
= 1 u + 15
= 6 + 15
= 21
Answer(s): 21
