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