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