Elyse and Winnie had the same number of beads. After Elyse had given away 80 beads, Winnie had 9 times as many beads as Elyse. How many beads did each of them have at first?
| |
Elyse |
Winnie |
| Before |
1 u + 80 |
9 u |
| Change |
- 80 |
|
| After |
1 u |
9 u |
Number of beads that Winnie had remains unchanged.
Number of beads that Elyse and Winnie had at first is equal.
9 u = 1 u + 80
9 u - 1 u = 80
8 u = 80
1 u = 80 ÷ 8= 10
Number of beads that each of them had at first
= 1 u + 80
= 10 + 80
= 90
Answer(s): 90
