Harry and Jade had the same number of mochi balls. After Jade gave away 18 mochi balls and Harry gave away 38 mochi balls, Jade had 2 times as many mochi balls as Harry. How many mochi balls did each of them have at first?
| |
Harry |
Jade |
| Before |
1 u + 38 |
2 u + 18 |
| Change |
- 38 |
- 18 |
| After |
1 u |
2 u |
The number of mochi balls that Harry and Jade had at first is the same.
2 u + 18 = 1 u + 38
2 u - 1 u = 38 - 18
1 u = 20
1 u = 20 ÷ 1 = 20
Number of mochi balls that each of them had at first
= 1 u + 38
= 20 + 38
= 58
Answer(s): 58
