Elyse and Anna had the same number of erasers. After Elyse had given away 64 erasers, Anna had 3 times as many erasers as Elyse. How many erasers did each of them have at first?
| |
Elyse |
Anna |
| Before |
1 u + 64 |
3 u |
| Change |
- 64 |
|
| After |
1 u |
3 u |
Number of erasers that Anna had remains unchanged.
Number of erasers that Elyse and Anna had at first is equal.
3 u = 1 u + 64
3 u - 1 u = 64
2 u = 64
1 u = 64 ÷ 2= 32
Number of erasers that each of them had at first
= 1 u + 64
= 32 + 64
= 96
Answer(s): 96
