Lee and Pamela had the same number of mochi balls. After Pamela gave away 19 mochi balls and Lee gave away 45 mochi balls, Pamela had 2 times as many mochi balls as Lee. How many mochi balls did each of them have at first?
| |
Lee |
Pamela |
| Before |
1 u + 45 |
2 u + 19 |
| Change |
- 45 |
- 19 |
| After |
1 u |
2 u |
The number of mochi balls that Lee and Pamela had at first is the same.
2 u + 19 = 1 u + 45
2 u - 1 u = 45 - 19
1 u = 26
1 u = 26 ÷ 1 = 26
Number of mochi balls that each of them had at first
= 1 u + 45
= 26 + 45
= 71
Answer(s): 71
