Ben and Julie had the same number of chocolate bars. After Julie gave away 12 chocolate bars and Ben gave away 50 chocolate bars, Julie had 2 times as many chocolate bars as Ben. How many chocolate bars did each of them have at first?
| |
Ben |
Julie |
| Before |
1 u + 50 |
2 u + 12 |
| Change |
- 50 |
- 12 |
| After |
1 u |
2 u |
The number of chocolate bars that Ben and Julie had at first is the same.
2 u + 12 = 1 u + 50
2 u - 1 u = 50 - 12
1 u = 38
1 u = 38 ÷ 1 = 38
Number of chocolate bars that each of them had at first
= 1 u + 50
= 38 + 50
= 88
Answer(s): 88
