Caleb and Sophia had an equal number of lollipops at first. After Caleb bought another 8 lollipops and Sophia lost 16 lollipops, Caleb had thrice as many lollipops as Sophia. Find the number of lollipops each of them had at first.
| |
Caleb |
Sophia |
| Before |
3 u - 8 |
1 u + 16 |
| Change |
+ 8 |
- 16 |
| After |
3 u |
1 u |
The number of lollipops that Caleb and Sophia at first is the same.
3 u - 8 = 1 u + 16
3 u - 1 u = 16 + 8
2 u = 24
1 u = 24 ÷ 2 = 12
Number of lollipops that each of them had at first
= 1 u + 16
= 12 + 16
= 28
Answer(s): 28
