Neave and Anna had the same number of mochi balls. After Anna gave away 20 mochi balls and Neave gave away 49 mochi balls, Anna had 2 times as many mochi balls as Neave. How many mochi balls did each of them have at first?
| |
Neave |
Anna |
| Before |
1 u + 49 |
2 u + 20 |
| Change |
- 49 |
- 20 |
| After |
1 u |
2 u |
The number of mochi balls that Neave and Anna had at first is the same.
2 u + 20 = 1 u + 49
2 u - 1 u = 49 - 20
1 u = 29
1 u = 29 ÷ 1 = 29
Number of mochi balls that each of them had at first
= 1 u + 49
= 29 + 49
= 78
Answer(s): 78
