Luke and Harris had an equal number of lollipops at first. After Luke bought another 5 lollipops and Harris lost 19 lollipops, Luke had thrice as many lollipops as Harris. Find the number of lollipops each of them had at first.
| |
Luke |
Harris |
| Before |
3 u - 5 |
1 u + 19 |
| Change |
+ 5 |
- 19 |
| After |
3 u |
1 u |
The number of lollipops that Luke and Harris at first is the same.
3 u - 5 = 1 u + 19
3 u - 1 u = 19 + 5
2 u = 24
1 u = 24 ÷ 2 = 12
Number of lollipops that each of them had at first
= 1 u + 19
= 12 + 19
= 31
Answer(s): 31
