Luke and Zoe had the same number of chocolate bars. After Zoe gave away 19 chocolate bars and Luke gave away 47 chocolate bars, Zoe had 5 times as many chocolate bars as Luke. How many chocolate bars did each of them have at first?
| |
Luke |
Zoe |
| Before |
1 u + 47 |
5 u + 19 |
| Change |
- 47 |
- 19 |
| After |
1 u |
5 u |
The number of chocolate bars that Luke and Zoe had at first is the same.
5 u + 19 = 1 u + 47
5 u - 1 u = 47 - 19
4 u = 28
1 u = 28 ÷ 4 = 7
Number of chocolate bars that each of them had at first
= 1 u + 47
= 7 + 47
= 54
Answer(s): 54
