Seth and Vanessa had the same number of mochi balls. After Vanessa gave away 19 mochi balls and Seth gave away 43 mochi balls, Vanessa had 3 times as many mochi balls as Seth. How many mochi balls did each of them have at first?
| |
Seth |
Vanessa |
| Before |
1 u + 43 |
3 u + 19 |
| Change |
- 43 |
- 19 |
| After |
1 u |
3 u |
The number of mochi balls that Seth and Vanessa had at first is the same.
3 u + 19 = 1 u + 43
3 u - 1 u = 43 - 19
2 u = 24
1 u = 24 ÷ 2 = 12
Number of mochi balls that each of them had at first
= 1 u + 43
= 12 + 43
= 55
Answer(s): 55
