Zoey |
Isaac |
| Before |
4 u - 17 |
1 u + 16 |
| Change |
+ 17 |
- 16 |
| After |
4 u |
1 u |
The number of caramel apples that Zoey and Isaac at first is the same.
4 u - 17 = 1 u + 16
4 u - 1 u = 16 + 17
3 u = 33
1 u = 33 ÷ 3 = 11
Number of caramel apples that each of them had at first
= 1 u + 16
= 11 + 16
= 27
Answer(s): 27
