Archie and Olivia had the same number of mochi balls. After Olivia gave away 13 mochi balls and Archie gave away 48 mochi balls, Olivia had 6 times as many mochi balls as Archie. How many mochi balls did each of them have at first?
| |
Archie |
Olivia |
| Before |
1 u + 48 |
6 u + 13 |
| Change |
- 48 |
- 13 |
| After |
1 u |
6 u |
The number of mochi balls that Archie and Olivia had at first is the same.
6 u + 13 = 1 u + 48
6 u - 1 u = 48 - 13
5 u = 35
1 u = 35 ÷ 5 = 7
Number of mochi balls that each of them had at first
= 1 u + 48
= 7 + 48
= 55
Answer(s): 55
