Caden and Eva had the same number of mochi balls. After Eva gave away 20 mochi balls and Caden gave away 53 mochi balls, Eva had 2 times as many mochi balls as Caden. How many mochi balls did each of them have at first?
| |
Caden |
Eva |
| Before |
1 u + 53 |
2 u + 20 |
| Change |
- 53 |
- 20 |
| After |
1 u |
2 u |
The number of mochi balls that Caden and Eva had at first is the same.
2 u + 20 = 1 u + 53
2 u - 1 u = 53 - 20
1 u = 33
1 u = 33 ÷ 1 = 33
Number of mochi balls that each of them had at first
= 1 u + 53
= 33 + 53
= 86
Answer(s): 86
