Josiah and Rachel had an equal number of lollipops at first. After Josiah bought another 4 lollipops and Rachel lost 12 lollipops, Josiah had thrice as many lollipops as Rachel. Find the number of lollipops each of them had at first.
| |
Josiah |
Rachel |
| Before |
3 u - 4 |
1 u + 12 |
| Change |
+ 4 |
- 12 |
| After |
3 u |
1 u |
The number of lollipops that Josiah and Rachel at first is the same.
3 u - 4 = 1 u + 12
3 u - 1 u = 12 + 4
2 u = 16
1 u = 16 ÷ 2 = 8
Number of lollipops that each of them had at first
= 1 u + 12
= 8 + 12
= 20
Answer(s): 20
