Elijah and Cathy had the same number of mochi balls. After Cathy gave away 13 mochi balls and Elijah gave away 46 mochi balls, Cathy had 4 times as many mochi balls as Elijah. How many mochi balls did each of them have at first?
| |
Elijah |
Cathy |
| Before |
1 u + 46 |
4 u + 13 |
| Change |
- 46 |
- 13 |
| After |
1 u |
4 u |
The number of mochi balls that Elijah and Cathy had at first is the same.
4 u + 13 = 1 u + 46
4 u - 1 u = 46 - 13
3 u = 33
1 u = 33 ÷ 3 = 11
Number of mochi balls that each of them had at first
= 1 u + 46
= 11 + 46
= 57
Answer(s): 57
