Ryan and Emily had the same number of chocolate bars. After Emily gave away 15 chocolate bars and Ryan gave away 55 chocolate bars, Emily had 5 times as many chocolate bars as Ryan. How many chocolate bars did each of them have at first?
| |
Ryan |
Emily |
| Before |
1 u + 55 |
5 u + 15 |
| Change |
- 55 |
- 15 |
| After |
1 u |
5 u |
The number of chocolate bars that Ryan and Emily had at first is the same.
5 u + 15 = 1 u + 55
5 u - 1 u = 55 - 15
4 u = 40
1 u = 40 ÷ 4 = 10
Number of chocolate bars that each of them had at first
= 1 u + 55
= 10 + 55
= 65
Answer(s): 65
