Vincent and Cathy had the same number of caramel apples. After Cathy gave away 18 caramel apples and Vincent gave away 51 caramel apples, Cathy had 2 times as many caramel apples as Vincent. How many caramel apples did each of them have at first?
| |
Vincent |
Cathy |
| Before |
1 u + 51 |
2 u + 18 |
| Change |
- 51 |
- 18 |
| After |
1 u |
2 u |
The number of caramel apples that Vincent and Cathy had at first is the same.
2 u + 18 = 1 u + 51
2 u - 1 u = 51 - 18
1 u = 33
1 u = 33 ÷ 1 = 33
Number of caramel apples that each of them had at first
= 1 u + 51
= 33 + 51
= 84
Answer(s): 84
