Mark and Kathy had the same number of caramel apples. After Kathy gave away 22 caramel apples and Mark gave away 43 caramel apples, Kathy had 2 times as many caramel apples as Mark. How many caramel apples did each of them have at first?
| |
Mark |
Kathy |
| Before |
1 u + 43 |
2 u + 22 |
| Change |
- 43 |
- 22 |
| After |
1 u |
2 u |
The number of caramel apples that Mark and Kathy had at first is the same.
2 u + 22 = 1 u + 43
2 u - 1 u = 43 - 22
1 u = 21
1 u = 21 ÷ 1 = 21
Number of caramel apples that each of them had at first
= 1 u + 43
= 21 + 43
= 64
Answer(s): 64
