John and Linda had the same number of chocolate bars. After Linda gave away 20 chocolate bars and John gave away 48 chocolate bars, Linda had 2 times as many chocolate bars as John. How many chocolate bars did each of them have at first?
| |
John |
Linda |
| Before |
1 u + 48 |
2 u + 20 |
| Change |
- 48 |
- 20 |
| After |
1 u |
2 u |
The number of chocolate bars that John and Linda had at first is the same.
2 u + 20 = 1 u + 48
2 u - 1 u = 48 - 20
1 u = 28
1 u = 28 ÷ 1 = 28
Number of chocolate bars that each of them had at first
= 1 u + 48
= 28 + 48
= 76
Answer(s): 76
