Pamela and Gwen had the same number of stickers. After Pamela had given away 63 stickers, Gwen had 8 times as many stickers as Pamela. How many stickers did each of them have at first?
| |
Pamela |
Gwen |
| Before |
1 u + 63 |
8 u |
| Change |
- 63 |
|
| After |
1 u |
8 u |
Number of stickers that Gwen had remains unchanged.
Number of stickers that Pamela and Gwen had at first is equal.
8 u = 1 u + 63
8 u - 1 u = 63
7 u = 63
1 u = 63 ÷ 7= 9
Number of stickers that each of them had at first
= 1 u + 63
= 9 + 63
= 72
Answer(s): 72
