Yen and Irene had the
same number of lollipops at first. Yen gave 14 lollipops away to her brother. In the end, Irene had three times as many lollipops as Yen. How many lollipops did Yen have at first?
| |
Yen |
Irene |
| Before |
3 u |
3 u |
| Change |
- 14 |
|
| After |
1 u |
3 u |
The number of lollipops that Irene had remains unchanged.
Number of lollipops that Yen gave away
= 3 u - 1 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Number of lollipops that Yen had at first
= 3 u
= 3 x 7
= 21
Answer(s): 21
