Cody and Tiffany had the same number of mini cupcakes. After Tiffany gave away 15 mini cupcakes and Cody gave away 39 mini cupcakes, Tiffany had 4 times as many mini cupcakes as Cody. How many mini cupcakes did each of them have at first?
| |
Cody |
Tiffany |
| Before |
1 u + 39 |
4 u + 15 |
| Change |
- 39 |
- 15 |
| After |
1 u |
4 u |
The number of mini cupcakes that Cody and Tiffany had at first is the same.
4 u + 15 = 1 u + 39
4 u - 1 u = 39 - 15
3 u = 24
1 u = 24 ÷ 3 = 8
Number of mini cupcakes that each of them had at first
= 1 u + 39
= 8 + 39
= 47
Answer(s): 47
