Archie and Opal had the same number of mini cupcakes. After Opal gave away 13 mini cupcakes and Archie gave away 52 mini cupcakes, Opal had 4 times as many mini cupcakes as Archie. How many mini cupcakes did each of them have at first?
| |
Archie |
Opal |
| Before |
1 u + 52 |
4 u + 13 |
| Change |
- 52 |
- 13 |
| After |
1 u |
4 u |
The number of mini cupcakes that Archie and Opal had at first is the same.
4 u + 13 = 1 u + 52
4 u - 1 u = 52 - 13
3 u = 39
1 u = 39 ÷ 3 = 13
Number of mini cupcakes that each of them had at first
= 1 u + 52
= 13 + 52
= 65
Answer(s): 65
