Sean and Emily had the same number of chocolate bars. After Emily gave away 19 chocolate bars and Sean gave away 43 chocolate bars, Emily had 4 times as many chocolate bars as Sean. How many chocolate bars did each of them have at first?
| |
Sean |
Emily |
| Before |
1 u + 43 |
4 u + 19 |
| Change |
- 43 |
- 19 |
| After |
1 u |
4 u |
The number of chocolate bars that Sean and Emily had at first is the same.
4 u + 19 = 1 u + 43
4 u - 1 u = 43 - 19
3 u = 24
1 u = 24 ÷ 3 = 8
Number of chocolate bars that each of them had at first
= 1 u + 43
= 8 + 43
= 51
Answer(s): 51
