David and Nicole had the same number of mochi balls. After Nicole gave away 22 mochi balls and David gave away 49 mochi balls, Nicole had 4 times as many mochi balls as David. How many mochi balls did each of them have at first?
| |
David |
Nicole |
| Before |
1 u + 49 |
4 u + 22 |
| Change |
- 49 |
- 22 |
| After |
1 u |
4 u |
The number of mochi balls that David and Nicole had at first is the same.
4 u + 22 = 1 u + 49
4 u - 1 u = 49 - 22
3 u = 27
1 u = 27 ÷ 3 = 9
Number of mochi balls that each of them had at first
= 1 u + 49
= 9 + 49
= 58
Answer(s): 58
