Ahmad and Emily had the same number of mochi balls. After Emily gave away 21 mochi balls and Ahmad gave away 53 mochi balls, Emily had 5 times as many mochi balls as Ahmad. How many mochi balls did each of them have at first?
| |
Ahmad |
Emily |
| Before |
1 u + 53 |
5 u + 21 |
| Change |
- 53 |
- 21 |
| After |
1 u |
5 u |
The number of mochi balls that Ahmad and Emily had at first is the same.
5 u + 21 = 1 u + 53
5 u - 1 u = 53 - 21
4 u = 32
1 u = 32 ÷ 4 = 8
Number of mochi balls that each of them had at first
= 1 u + 53
= 8 + 53
= 61
Answer(s): 61
