Xandra and Gwen had the same number of beads. After Xandra had given away 60 beads, Gwen had 6 times as many beads as Xandra. How many beads did each of them have at first?
| |
Xandra |
Gwen |
| Before |
1 u + 60 |
6 u |
| Change |
- 60 |
|
| After |
1 u |
6 u |
Number of beads that Gwen had remains unchanged.
Number of beads that Xandra and Gwen had at first is equal.
6 u = 1 u + 60
6 u - 1 u = 60
5 u = 60
1 u = 60 ÷ 5= 12
Number of beads that each of them had at first
= 1 u + 60
= 12 + 60
= 72
Answer(s): 72
