Bobby and Eva had the same number of mini cupcakes. After Eva gave away 17 mini cupcakes and Bobby gave away 49 mini cupcakes, Eva had 2 times as many mini cupcakes as Bobby. How many mini cupcakes did each of them have at first?
| |
Bobby |
Eva |
| Before |
1 u + 49 |
2 u + 17 |
| Change |
- 49 |
- 17 |
| After |
1 u |
2 u |
The number of mini cupcakes that Bobby and Eva had at first is the same.
2 u + 17 = 1 u + 49
2 u - 1 u = 49 - 17
1 u = 32
1 u = 32 ÷ 1 = 32
Number of mini cupcakes that each of them had at first
= 1 u + 49
= 32 + 49
= 81
Answer(s): 81
