Jaslyn and Shiyun had the same number of stickers. After Jaslyn had given away 80 stickers, Shiyun had 5 times as many stickers as Jaslyn. How many stickers did each of them have at first?
| |
Jaslyn |
Shiyun |
| Before |
1 u + 80 |
5 u |
| Change |
- 80 |
|
| After |
1 u |
5 u |
Number of stickers that Shiyun had remains unchanged.
Number of stickers that Jaslyn and Shiyun had at first is equal.
5 u = 1 u + 80
5 u - 1 u = 80
4 u = 80
1 u = 80 ÷ 4= 20
Number of stickers that each of them had at first
= 1 u + 80
= 20 + 80
= 100
Answer(s): 100
