Mia and Caleb had an equal number of mini cupcakes at first. After Mia bought another 17 mini cupcakes and Caleb lost 16 mini cupcakes, Mia had four times as many mini cupcakes as Caleb. Find the number of mini cupcakes each of them had at first.

| Before |
4 u - 17 |
1 u + 16 |
| Change |
+ 17 |
- 16 |
| After |
4 u |
1 u |
The number of mini cupcakes that Mia and Caleb at first is the same.
4 u - 17 = 1 u + 16
4 u - 1 u = 16 + 17
3 u = 33
1 u = 33 ÷ 3 = 11
Number of mini cupcakes that each of them had at first
= 1 u + 16
= 11 + 16
= 27
Answer(s): 27
