Owen and Erika had the same number of chocolate bars. After Erika gave away 20 chocolate bars and Owen gave away 48 chocolate bars, Erika had 3 times as many chocolate bars as Owen. How many chocolate bars did each of them have at first?
| |
Owen |
Erika |
| Before |
1 u + 48 |
3 u + 20 |
| Change |
- 48 |
- 20 |
| After |
1 u |
3 u |
The number of chocolate bars that Owen and Erika had at first is the same.
3 u + 20 = 1 u + 48
3 u - 1 u = 48 - 20
2 u = 28
1 u = 28 ÷ 2 = 14
Number of chocolate bars that each of them had at first
= 1 u + 48
= 14 + 48
= 62
Answer(s): 62
