Jean and Elyse had the
same number of lollipops at first. Jean gave 10 lollipops away to her brother. In the end, Elyse had three times as many lollipops as Jean. How many lollipops did Jean have at first?
| |
Jean |
Elyse |
| Before |
3 u |
3 u |
| Change |
- 10 |
|
| After |
1 u |
3 u |
The number of lollipops that Elyse had remains unchanged.
Number of lollipops that Jean gave away
= 3 u - 1 u
= 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of lollipops that Jean had at first
= 3 u
= 3 x 5
= 15
Answer(s): 15
