Irene and Raeann had the
same number of mini cupcakes at first. Irene gave 27 mini cupcakes away to her sister. In the end, Raeann had four times as many mini cupcakes as Irene. How many mini cupcakes did Irene have at first?
|
Irene |
Raeann |
Before |
4 u |
4 u |
Change |
- 27 |
|
After |
1 u |
4 u |
The number of mini cupcakes that Raeann had remains unchanged.
Number of mini cupcakes that Irene gave away
= 4 u - 1 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Number of mini cupcakes that Irene had at first
= 4 u
= 4 x 9
= 36
Answer(s): 36
