Charlie and Ivory had the same number of mochi balls. After Ivory gave away 20 mochi balls and Charlie gave away 44 mochi balls, Ivory had 3 times as many mochi balls as Charlie. How many mochi balls did each of them have at first?
| |
Charlie |
Ivory |
| Before |
1 u + 44 |
3 u + 20 |
| Change |
- 44 |
- 20 |
| After |
1 u |
3 u |
The number of mochi balls that Charlie and Ivory had at first is the same.
3 u + 20 = 1 u + 44
3 u - 1 u = 44 - 20
2 u = 24
1 u = 24 ÷ 2 = 12
Number of mochi balls that each of them had at first
= 1 u + 44
= 12 + 44
= 56
Answer(s): 56
