Ryan |
Ethan |
| Before |
1 u + 49 |
5 u + 9 |
| Change |
- 49 |
- 9 |
| After |
1 u |
5 u |
Ryan and Ethan had an equal number of chocolate bars at first.
5 u + 9 = 1 u + 49
5 u - 1 u = 49 - 9
4 u = 40
1 u = 40 ÷ 4 = 10
Number of chocolate bars that each of them had at first
= 1 u + 49
= 10 + 49
= 59
Answer(s): 59
