| |
Carl |
Will |
| Before |
1 u + 28 |
3 u + 2 |
| Change |
- 28 |
- 2 |
| After |
1 u |
3 u |
Carl and Will had an equal number of mochi balls at first.
3 u + 2 = 1 u + 28
3 u - 1 u = 28 - 2
2 u = 26
1 u = 26 ÷ 2 = 13
Number of mochi balls that each of them had at first
= 1 u + 28
= 13 + 28
= 41
Answer(s): 41
