Cole and Julie had the same number of mochi balls. After Julie gave away 18 mochi balls and Cole gave away 37 mochi balls, Julie had 2 times as many mochi balls as Cole. How many mochi balls did each of them have at first?
| |
Cole |
Julie |
| Before |
1 u + 37 |
2 u + 18 |
| Change |
- 37 |
- 18 |
| After |
1 u |
2 u |
The number of mochi balls that Cole and Julie had at first is the same.
2 u + 18 = 1 u + 37
2 u - 1 u = 37 - 18
1 u = 19
1 u = 19 ÷ 1 = 19
Number of mochi balls that each of them had at first
= 1 u + 37
= 19 + 37
= 56
Answer(s): 56
