Warren and Kimberly had the same number of chocolate bars. After Kimberly gave away 22 chocolate bars and Warren gave away 50 chocolate bars, Kimberly had 2 times as many chocolate bars as Warren. How many chocolate bars did each of them have at first?
| |
Warren |
Kimberly |
| Before |
1 u + 50 |
2 u + 22 |
| Change |
- 50 |
- 22 |
| After |
1 u |
2 u |
The number of chocolate bars that Warren and Kimberly had at first is the same.
2 u + 22 = 1 u + 50
2 u - 1 u = 50 - 22
1 u = 28
1 u = 28 ÷ 1 = 28
Number of chocolate bars that each of them had at first
= 1 u + 50
= 28 + 50
= 78
Answer(s): 78
