| |
Daniel |
Liam |
| Before |
1 u + 36 |
4 u + 9 |
| Change |
- 36 |
- 9 |
| After |
1 u |
4 u |
Daniel and Liam had an equal number of mini cupcakes at first.
4 u + 9 = 1 u + 36
4 u - 1 u = 36 - 9
3 u = 27
1 u = 27 ÷ 3 = 9
Number of mini cupcakes that each of them had at first
= 1 u + 36
= 9 + 36
= 45
Answer(s): 45
