Zeph and Nora had the same number of chocolate bars. After Nora gave away 16 chocolate bars and Zeph gave away 43 chocolate bars, Nora had 2 times as many chocolate bars as Zeph. How many chocolate bars did each of them have at first?
| |
Zeph |
Nora |
| Before |
1 u + 43 |
2 u + 16 |
| Change |
- 43 |
- 16 |
| After |
1 u |
2 u |
The number of chocolate bars that Zeph and Nora had at first is the same.
2 u + 16 = 1 u + 43
2 u - 1 u = 43 - 16
1 u = 27
1 u = 27 ÷ 1 = 27
Number of chocolate bars that each of them had at first
= 1 u + 43
= 27 + 43
= 70
Answer(s): 70
