Rael and Lynn had the same number of mini cupcakes. After Lynn gave away 17 mini cupcakes and Rael gave away 38 mini cupcakes, Lynn had 4 times as many mini cupcakes as Rael. How many mini cupcakes did each of them have at first?
| |
Rael |
Lynn |
| Before |
1 u + 38 |
4 u + 17 |
| Change |
- 38 |
- 17 |
| After |
1 u |
4 u |
The number of mini cupcakes that Rael and Lynn had at first is the same.
4 u + 17 = 1 u + 38
4 u - 1 u = 38 - 17
3 u = 21
1 u = 21 ÷ 3 = 7
Number of mini cupcakes that each of them had at first
= 1 u + 38
= 7 + 38
= 45
Answer(s): 45
