Rachel and Lynn had the same number of stickers. After Rachel had given away 64 stickers, Lynn had 9 times as many stickers as Rachel. How many stickers did each of them have at first?
|
Rachel |
Lynn |
Before |
1 u + 64 |
9 u |
Change |
- 64 |
|
After |
1 u |
9 u |
Number of stickers that Lynn had remains unchanged.
Number of stickers that Rachel and Lynn had at first is equal.
9 u = 1 u + 64
9 u - 1 u = 64
8 u = 64
1 u = 64 ÷ 8= 8
Number of stickers that each of them had at first
= 1 u + 64
= 8 + 64
= 72
Answer(s): 72
