Zane and Julie had the same number of chocolate bars. After Julie gave away 12 chocolate bars and Zane gave away 40 chocolate bars, Julie had 2 times as many chocolate bars as Zane. How many chocolate bars did each of them have at first?
| |
Zane |
Julie |
| Before |
1 u + 40 |
2 u + 12 |
| Change |
- 40 |
- 12 |
| After |
1 u |
2 u |
The number of chocolate bars that Zane and Julie had at first is the same.
2 u + 12 = 1 u + 40
2 u - 1 u = 40 - 12
1 u = 28
1 u = 28 ÷ 1 = 28
Number of chocolate bars that each of them had at first
= 1 u + 40
= 28 + 40
= 68
Answer(s): 68
