Will and Linda had the same number of mochi balls. After Linda gave away 18 mochi balls and Will gave away 36 mochi balls, Linda had 2 times as many mochi balls as Will. How many mochi balls did each of them have at first?
| |
Will |
Linda |
| Before |
1 u + 36 |
2 u + 18 |
| Change |
- 36 |
- 18 |
| After |
1 u |
2 u |
The number of mochi balls that Will and Linda had at first is the same.
2 u + 18 = 1 u + 36
2 u - 1 u = 36 - 18
1 u = 18
1 u = 18 ÷ 1 = 18
Number of mochi balls that each of them had at first
= 1 u + 36
= 18 + 36
= 54
Answer(s): 54
