Oscar and Kimberly had the same number of chocolate bars. After Kimberly gave away 18 chocolate bars and Oscar gave away 44 chocolate bars, Kimberly had 2 times as many chocolate bars as Oscar. How many chocolate bars did each of them have at first?
| |
Oscar |
Kimberly |
| Before |
1 u + 44 |
2 u + 18 |
| Change |
- 44 |
- 18 |
| After |
1 u |
2 u |
The number of chocolate bars that Oscar and Kimberly had at first is the same.
2 u + 18 = 1 u + 44
2 u - 1 u = 44 - 18
1 u = 26
1 u = 26 ÷ 1 = 26
Number of chocolate bars that each of them had at first
= 1 u + 44
= 26 + 44
= 70
Answer(s): 70
