Gabriel and Barbara had the same number of mini cupcakes. After Barbara gave away 15 mini cupcakes and Gabriel gave away 48 mini cupcakes, Barbara had 2 times as many mini cupcakes as Gabriel. How many mini cupcakes did each of them have at first?
| |
Gabriel |
Barbara |
| Before |
1 u + 48 |
2 u + 15 |
| Change |
- 48 |
- 15 |
| After |
1 u |
2 u |
The number of mini cupcakes that Gabriel and Barbara had at first is the same.
2 u + 15 = 1 u + 48
2 u - 1 u = 48 - 15
1 u = 33
1 u = 33 ÷ 1 = 33
Number of mini cupcakes that each of them had at first
= 1 u + 48
= 33 + 48
= 81
Answer(s): 81
