Rael and Lilian had an equal number of mini cupcakes at first. After Rael bought another 3 mini cupcakes and Lilian lost 25 mini cupcakes, Rael had five times as many mini cupcakes as Lilian. Find the number of mini cupcakes each of them had at first.

Rael |
Lilian |
| Before |
5 u - 3 |
1 u + 25 |
| Change |
+ 3 |
- 25 |
| After |
5 u |
1 u |
The number of mini cupcakes that Rael and Lilian at first is the same.
5 u - 3 = 1 u + 25
5 u - 1 u = 25 + 3
4 u = 28
1 u = 28 ÷ 4 = 7
Number of mini cupcakes that each of them had at first
= 1 u + 25
= 7 + 25
= 32
Answer(s): 32
