Jack and Anna had the same number of mini cupcakes. After Anna gave away 16 mini cupcakes and Jack gave away 43 mini cupcakes, Anna had 2 times as many mini cupcakes as Jack. How many mini cupcakes did each of them have at first?
| |
Jack |
Anna |
| Before |
1 u + 43 |
2 u + 16 |
| Change |
- 43 |
- 16 |
| After |
1 u |
2 u |
The number of mini cupcakes that Jack and Anna had at first is the same.
2 u + 16 = 1 u + 43
2 u - 1 u = 43 - 16
1 u = 27
1 u = 27 ÷ 1 = 27
Number of mini cupcakes that each of them had at first
= 1 u + 43
= 27 + 43
= 70
Answer(s): 70
