Gwen and Zoe had an equal number of mini cupcakes. After Gwen bought another 30 mini cupcakes and Zoe bought another 6 mini cupcakes, Gwen had four times as many mini cupcakes as Zoe. Find the number of mini cupcakes that each of them had at first.

Gwen |
Zoe |
| Before |
4 u - 30 |
1 u - 6 |
| Change |
+ 30 |
+ 6 |
| After |
4 u |
1 u |
The number of mini cupcakes that Gwen and Zoe had at first is the same.
4 u - 30 = 1 u - 6
4 u - 1 u = 30 - 6
3 u = 24
1 u = 24 ÷ 3 = 8
Number of mini cupcakes that each had at first
= 8 - 6
= 2
Answer(s): 2
