Simon and Rachel had the same number of mini cupcakes. After Rachel gave away 19 mini cupcakes and Simon gave away 39 mini cupcakes, Rachel had 5 times as many mini cupcakes as Simon. How many mini cupcakes did each of them have at first?
| |
Simon |
Rachel |
| Before |
1 u + 39 |
5 u + 19 |
| Change |
- 39 |
- 19 |
| After |
1 u |
5 u |
The number of mini cupcakes that Simon and Rachel had at first is the same.
5 u + 19 = 1 u + 39
5 u - 1 u = 39 - 19
4 u = 20
1 u = 20 ÷ 4 = 5
Number of mini cupcakes that each of them had at first
= 1 u + 39
= 5 + 39
= 44
Answer(s): 44
