Isaac and Raeann had an equal number of caramel apples at first. After Isaac bought another 10 caramel apples and Raeann lost 22 caramel apples, Isaac had thrice as many caramel apples as Raeann. Find the number of caramel apples each of them had at first.
| |
Isaac |
Raeann |
| Before |
3 u - 10 |
1 u + 22 |
| Change |
+ 10 |
- 22 |
| After |
3 u |
1 u |
The number of caramel apples that Isaac and Raeann at first is the same.
3 u - 10 = 1 u + 22
3 u - 1 u = 22 + 10
2 u = 32
1 u = 32 ÷ 2 = 16
Number of caramel apples that each of them had at first
= 1 u + 22
= 16 + 22
= 38
Answer(s): 38
