Riordan and Xuan had the same number of lollipops. After Xuan gave away 17 lollipops and Riordan gave away 38 lollipops, Xuan had 4 times as many lollipops as Riordan. How many lollipops did each of them have at first?
| |
Riordan |
Xuan |
| Before |
1 u + 38 |
4 u + 17 |
| Change |
- 38 |
- 17 |
| After |
1 u |
4 u |
The number of lollipops that Riordan and Xuan had at first is the same.
4 u + 17 = 1 u + 38
4 u - 1 u = 38 - 17
3 u = 21
1 u = 21 ÷ 3 = 7
Number of lollipops that each of them had at first
= 1 u + 38
= 7 + 38
= 45
Answer(s): 45
