Sophia and Jeremiah had an equal number of mini cupcakes at first. After Sophia bought another 8 mini cupcakes and Jeremiah lost 28 mini cupcakes, Sophia had four times as many mini cupcakes as Jeremiah. Find the number of mini cupcakes each of them had at first.

Sophia |
Jeremiah |
| Before |
4 u - 8 |
1 u + 28 |
| Change |
+ 8 |
- 28 |
| After |
4 u |
1 u |
The number of mini cupcakes that Sophia and Jeremiah at first is the same.
4 u - 8 = 1 u + 28
4 u - 1 u = 28 + 8
3 u = 36
1 u = 36 ÷ 3 = 12
Number of mini cupcakes that each of them had at first
= 1 u + 28
= 12 + 28
= 40
Answer(s): 40
