Jeremy and Joelle had the same number of chocolate bars. After Joelle gave away 18 chocolate bars and Jeremy gave away 54 chocolate bars, Joelle had 4 times as many chocolate bars as Jeremy. How many chocolate bars did each of them have at first?
| |
Jeremy |
Joelle |
| Before |
1 u + 54 |
4 u + 18 |
| Change |
- 54 |
- 18 |
| After |
1 u |
4 u |
The number of chocolate bars that Jeremy and Joelle had at first is the same.
4 u + 18 = 1 u + 54
4 u - 1 u = 54 - 18
3 u = 36
1 u = 36 ÷ 3 = 12
Number of chocolate bars that each of them had at first
= 1 u + 54
= 12 + 54
= 66
Answer(s): 66
