Nora and Marion had an equal number of lollipops. After Nora bought another 30 lollipops and Marion bought another 6 lollipops, Nora had thrice as many lollipops as Marion. Find the number of lollipops that each of them had at first.

Nora |
Marion |
| Before |
3 u - 30 |
1 u - 6 |
| Change |
+ 30 |
+ 6 |
| After |
3 u |
1 u |
The number of lollipops that Nora and Marion had at first is the same.
3 u - 30 = 1 u - 6
3 u - 1 u = 30 - 6
2 u = 24
1 u = 24 ÷ 2 = 12
Number of lollipops that each had at first
= 12 - 6
= 6
Answer(s): 6
