John and Hilda had the same number of mini cupcakes. After Hilda gave away 22 mini cupcakes and John gave away 45 mini cupcakes, Hilda had 2 times as many mini cupcakes as John. How many mini cupcakes did each of them have at first?
| |
John |
Hilda |
| Before |
1 u + 45 |
2 u + 22 |
| Change |
- 45 |
- 22 |
| After |
1 u |
2 u |
The number of mini cupcakes that John and Hilda had at first is the same.
2 u + 22 = 1 u + 45
2 u - 1 u = 45 - 22
1 u = 23
1 u = 23 ÷ 1 = 23
Number of mini cupcakes that each of them had at first
= 1 u + 45
= 23 + 45
= 68
Answer(s): 68
