Riordan |
Noah |
| Before |
3 u - 18 |
1 u + 28 |
| Change |
+ 18 |
- 28 |
| After |
3 u |
1 u |
The number of caramel apples that Riordan and Noah at first is the same.
3 u - 18 = 1 u + 28
3 u - 1 u = 28 + 18
2 u = 46
1 u = 46 ÷ 2 = 23
Number of caramel apples that each of them had at first
= 1 u + 28
= 23 + 28
= 51
Answer(s): 51
