Cole and Gabby had the same number of chocolate bars. After Gabby gave away 21 chocolate bars and Cole gave away 41 chocolate bars, Gabby had 6 times as many chocolate bars as Cole. How many chocolate bars did each of them have at first?
| |
Cole |
Gabby |
| Before |
1 u + 41 |
6 u + 21 |
| Change |
- 41 |
- 21 |
| After |
1 u |
6 u |
The number of chocolate bars that Cole and Gabby had at first is the same.
6 u + 21 = 1 u + 41
6 u - 1 u = 41 - 21
5 u = 20
1 u = 20 ÷ 5 = 4
Number of chocolate bars that each of them had at first
= 1 u + 41
= 4 + 41
= 45
Answer(s): 45
