Wesley and Irene had the same number of mochi balls. After Irene gave away 18 mochi balls and Wesley gave away 38 mochi balls, Irene had 6 times as many mochi balls as Wesley. How many mochi balls did each of them have at first?
| |
Wesley |
Irene |
| Before |
1 u + 38 |
6 u + 18 |
| Change |
- 38 |
- 18 |
| After |
1 u |
6 u |
The number of mochi balls that Wesley and Irene had at first is the same.
6 u + 18 = 1 u + 38
6 u - 1 u = 38 - 18
5 u = 20
1 u = 20 ÷ 5 = 4
Number of mochi balls that each of them had at first
= 1 u + 38
= 4 + 38
= 42
Answer(s): 42
