Brandon and Jean had the same number of mochi balls. After Jean gave away 13 mochi balls and Brandon gave away 43 mochi balls, Jean had 2 times as many mochi balls as Brandon. How many mochi balls did each of them have at first?
| |
Brandon |
Jean |
| Before |
1 u + 43 |
2 u + 13 |
| Change |
- 43 |
- 13 |
| After |
1 u |
2 u |
The number of mochi balls that Brandon and Jean had at first is the same.
2 u + 13 = 1 u + 43
2 u - 1 u = 43 - 13
1 u = 30
1 u = 30 ÷ 1 = 30
Number of mochi balls that each of them had at first
= 1 u + 43
= 30 + 43
= 73
Answer(s): 73
