Howard and Shannon had the same number of mochi balls. After Shannon gave away 15 mochi balls and Howard gave away 55 mochi balls, Shannon had 2 times as many mochi balls as Howard. How many mochi balls did each of them have at first?
| |
Howard |
Shannon |
| Before |
1 u + 55 |
2 u + 15 |
| Change |
- 55 |
- 15 |
| After |
1 u |
2 u |
The number of mochi balls that Howard and Shannon had at first is the same.
2 u + 15 = 1 u + 55
2 u - 1 u = 55 - 15
1 u = 40
1 u = 40 ÷ 1 = 40
Number of mochi balls that each of them had at first
= 1 u + 55
= 40 + 55
= 95
Answer(s): 95
