Jack and Mary had the same number of caramel apples. After Mary gave away 12 caramel apples and Jack gave away 48 caramel apples, Mary had 3 times as many caramel apples as Jack. How many caramel apples did each of them have at first?
| |
Jack |
Mary |
| Before |
1 u + 48 |
3 u + 12 |
| Change |
- 48 |
- 12 |
| After |
1 u |
3 u |
The number of caramel apples that Jack and Mary had at first is the same.
3 u + 12 = 1 u + 48
3 u - 1 u = 48 - 12
2 u = 36
1 u = 36 ÷ 2 = 18
Number of caramel apples that each of them had at first
= 1 u + 48
= 18 + 48
= 66
Answer(s): 66
