Bryan and Fiona had the same number of mini cupcakes. After Fiona gave away 12 mini cupcakes and Bryan gave away 36 mini cupcakes, Fiona had 3 times as many mini cupcakes as Bryan. How many mini cupcakes did each of them have at first?
| |
Bryan |
Fiona |
| Before |
1 u + 36 |
3 u + 12 |
| Change |
- 36 |
- 12 |
| After |
1 u |
3 u |
The number of mini cupcakes that Bryan and Fiona had at first is the same.
3 u + 12 = 1 u + 36
3 u - 1 u = 36 - 12
2 u = 24
1 u = 24 ÷ 2 = 12
Number of mini cupcakes that each of them had at first
= 1 u + 36
= 12 + 36
= 48
Answer(s): 48
