Pierre and Usha had the same number of caramel apples. After Usha gave away 21 caramel apples and Pierre gave away 42 caramel apples, Usha had 4 times as many caramel apples as Pierre. How many caramel apples did each of them have at first?
| |
Pierre |
Usha |
| Before |
1 u + 42 |
4 u + 21 |
| Change |
- 42 |
- 21 |
| After |
1 u |
4 u |
The number of caramel apples that Pierre and Usha had at first is the same.
4 u + 21 = 1 u + 42
4 u - 1 u = 42 - 21
3 u = 21
1 u = 21 ÷ 3 = 7
Number of caramel apples that each of them had at first
= 1 u + 42
= 7 + 42
= 49
Answer(s): 49
