Albert and Esther had the same number of chocolate bars. After Esther gave away 20 chocolate bars and Albert gave away 36 chocolate bars, Esther had 3 times as many chocolate bars as Albert. How many chocolate bars did each of them have at first?
| |
Albert |
Esther |
| Before |
1 u + 36 |
3 u + 20 |
| Change |
- 36 |
- 20 |
| After |
1 u |
3 u |
The number of chocolate bars that Albert and Esther had at first is the same.
3 u + 20 = 1 u + 36
3 u - 1 u = 36 - 20
2 u = 16
1 u = 16 ÷ 2 = 8
Number of chocolate bars that each of them had at first
= 1 u + 36
= 8 + 36
= 44
Answer(s): 44
