Total |
| Before |
1 u + 11 + 25 |
1 u + 11 |
5 u + 11 |
| Change |
|
- 11 |
|
| After |
4 u |
1 u |

The number of mini cupcakes that Kathy had at first remains unchanged.
4 u = 1 u + 11 + 25
4 u - 1 u = 36
3 u = 36
1 u = 36 ÷ 3 = 12
Number of mini cupcakes that they had at first
= 5 u + 11
= 5 x 12 + 11
= 60 + 11
= 71
Answer(s): 71
