Gabriel and Scarlett had an equal number of mini cupcakes at first. After Gabriel bought another 6 mini cupcakes and Scarlett lost 24 mini cupcakes, Gabriel had thrice as many mini cupcakes as Scarlett. Find the number of mini cupcakes each of them had at first.
| |
Gabriel |
Scarlett |
| Before |
3 u - 6 |
1 u + 24 |
| Change |
+ 6 |
- 24 |
| After |
3 u |
1 u |
The number of mini cupcakes that Gabriel and Scarlett at first is the same.
3 u - 6 = 1 u + 24
3 u - 1 u = 24 + 6
2 u = 30
1 u = 30 ÷ 2 = 15
Number of mini cupcakes that each of them had at first
= 1 u + 24
= 15 + 24
= 39
Answer(s): 39
