Henry and Sofia had an equal number of mini cupcakes at first. After Henry bought another 4 mini cupcakes and Sofia lost 8 mini cupcakes, Henry had thrice as many mini cupcakes as Sofia. Find the number of mini cupcakes each of them had at first.
| |
Henry |
Sofia |
| Before |
3 u - 4 |
1 u + 8 |
| Change |
+ 4 |
- 8 |
| After |
3 u |
1 u |
The number of mini cupcakes that Henry and Sofia at first is the same.
3 u - 4 = 1 u + 8
3 u - 1 u = 8 + 4
2 u = 12
1 u = 12 ÷ 2 = 6
Number of mini cupcakes that each of them had at first
= 1 u + 8
= 6 + 8
= 14
Answer(s): 14
