Tom and Mary had the same number of caramel apples. After Mary gave away 12 caramel apples and Tom gave away 36 caramel apples, Mary had 2 times as many caramel apples as Tom. How many caramel apples did each of them have at first?
| |
Tom |
Mary |
| Before |
1 u + 36 |
2 u + 12 |
| Change |
- 36 |
- 12 |
| After |
1 u |
2 u |
The number of caramel apples that Tom and Mary had at first is the same.
2 u + 12 = 1 u + 36
2 u - 1 u = 36 - 12
1 u = 24
1 u = 24 ÷ 1 = 24
Number of caramel apples that each of them had at first
= 1 u + 36
= 24 + 36
= 60
Answer(s): 60
