Dylan and Eva had the same number of mini cupcakes. After Eva gave away 15 mini cupcakes and Dylan gave away 45 mini cupcakes, Eva had 3 times as many mini cupcakes as Dylan. How many mini cupcakes did each of them have at first?
| |
Dylan |
Eva |
| Before |
1 u + 45 |
3 u + 15 |
| Change |
- 45 |
- 15 |
| After |
1 u |
3 u |
The number of mini cupcakes that Dylan and Eva had at first is the same.
3 u + 15 = 1 u + 45
3 u - 1 u = 45 - 15
2 u = 30
1 u = 30 ÷ 2 = 15
Number of mini cupcakes that each of them had at first
= 1 u + 45
= 15 + 45
= 60
Answer(s): 60
