Total |
| Before |
1 u + 15 + 33 |
1 u + 15 |
6 u + 15 |
| Change |
|
- 15 |

| After |
5 u |
1 u |

The number of mini cupcakes that Nora had at first remains unchanged.
5 u = 1 u + 15 + 33
5 u - 1 u = 48
4 u = 48
1 u = 48 ÷ 4 = 12
Number of mini cupcakes that they had at first
= 6 u + 15
= 6 x 12 + 15
= 72 + 15
= 87
Answer(s): 87
