David and Erika had the same number of caramel apples. After Erika gave away 20 caramel apples and David gave away 53 caramel apples, Erika had 2 times as many caramel apples as David. How many caramel apples did each of them have at first?
| |
David |
Erika |
| Before |
1 u + 53 |
2 u + 20 |
| Change |
- 53 |
- 20 |
| After |
1 u |
2 u |
The number of caramel apples that David and Erika had at first is the same.
2 u + 20 = 1 u + 53
2 u - 1 u = 53 - 20
1 u = 33
1 u = 33 ÷ 1 = 33
Number of caramel apples that each of them had at first
= 1 u + 53
= 33 + 53
= 86
Answer(s): 86
