Michael and Erika had the same number of mochi balls. After Erika gave away 17 mochi balls and Michael gave away 35 mochi balls, Erika had 4 times as many mochi balls as Michael. How many mochi balls did each of them have at first?
| |
Michael |
Erika |
| Before |
1 u + 35 |
4 u + 17 |
| Change |
- 35 |
- 17 |
| After |
1 u |
4 u |
The number of mochi balls that Michael and Erika had at first is the same.
4 u + 17 = 1 u + 35
4 u - 1 u = 35 - 17
3 u = 18
1 u = 18 ÷ 3 = 6
Number of mochi balls that each of them had at first
= 1 u + 35
= 6 + 35
= 41
Answer(s): 41
