Gavin and Olivia had an equal number of lollipops at first. After Gavin bought another 4 lollipops and Olivia lost 14 lollipops, Gavin had four times as many lollipops as Olivia. Find the number of lollipops each of them had at first.
|
Gavin |
Olivia |
Before |
4 u - 4 |
1 u + 14 |
Change |
+ 4 |
- 14 |
After |
4 u |
1 u |
The number of lollipops that Gavin and Olivia at first is the same.
4 u - 4 = 1 u + 14
4 u - 1 u = 14 + 4
3 u = 18
1 u = 18 ÷ 3 = 6
Number of lollipops that each of them had at first
= 1 u + 14
= 6 + 14
= 20
Answer(s): 20
