| Before |
4 u - 12 |
1 u + 18 |
| Change |
+ 12 |
- 18 |
| After |
4 u |
1 u |
The number of caramel apples that Elijah and Grace at first is the same.
4 u - 12 = 1 u + 18
4 u - 1 u = 18 + 12
3 u = 30
1 u = 30 ÷ 3 = 10
Number of caramel apples that each of them had at first
= 1 u + 18
= 10 + 18
= 28
Answer(s): 28
