Julian and Irene had the same number of mochi balls. After Irene gave away 14 mochi balls and Julian gave away 47 mochi balls, Irene had 2 times as many mochi balls as Julian. How many mochi balls did each of them have at first?
| |
Julian |
Irene |
| Before |
1 u + 47 |
2 u + 14 |
| Change |
- 47 |
- 14 |
| After |
1 u |
2 u |
The number of mochi balls that Julian and Irene had at first is the same.
2 u + 14 = 1 u + 47
2 u - 1 u = 47 - 14
1 u = 33
1 u = 33 ÷ 1 = 33
Number of mochi balls that each of them had at first
= 1 u + 47
= 33 + 47
= 80
Answer(s): 80
