Sean and Mary had the same number of caramel apples. After Mary gave away 20 caramel apples and Sean gave away 38 caramel apples, Mary had 2 times as many caramel apples as Sean. How many caramel apples did each of them have at first?
| |
Sean |
Mary |
| Before |
1 u + 38 |
2 u + 20 |
| Change |
- 38 |
- 20 |
| After |
1 u |
2 u |
The number of caramel apples that Sean and Mary had at first is the same.
2 u + 20 = 1 u + 38
2 u - 1 u = 38 - 20
1 u = 18
1 u = 18 ÷ 1 = 18
Number of caramel apples that each of them had at first
= 1 u + 38
= 18 + 38
= 56
Answer(s): 56
