Mia and Victoria had an equal number of mini cupcakes at first. After Mia bought another 11 mini cupcakes and Victoria lost 13 mini cupcakes, Mia had thrice as many mini cupcakes as Victoria. Find the number of mini cupcakes each of them had at first.
| |
Mia |
Victoria |
| Before |
3 u - 11 |
1 u + 13 |
| Change |
+ 11 |
- 13 |
| After |
3 u |
1 u |
The number of mini cupcakes that Mia and Victoria at first is the same.
3 u - 11 = 1 u + 13
3 u - 1 u = 13 + 11
2 u = 24
1 u = 24 ÷ 2 = 12
Number of mini cupcakes that each of them had at first
= 1 u + 13
= 12 + 13
= 25
Answer(s): 25
