Eric and Shannon had the same number of mochi balls. After Shannon gave away 22 mochi balls and Eric gave away 42 mochi balls, Shannon had 6 times as many mochi balls as Eric. How many mochi balls did each of them have at first?
| |
Eric |
Shannon |
| Before |
1 u + 42 |
6 u + 22 |
| Change |
- 42 |
- 22 |
| After |
1 u |
6 u |
The number of mochi balls that Eric and Shannon had at first is the same.
6 u + 22 = 1 u + 42
6 u - 1 u = 42 - 22
5 u = 20
1 u = 20 ÷ 5 = 4
Number of mochi balls that each of them had at first
= 1 u + 42
= 4 + 42
= 46
Answer(s): 46
