Nora had 29 more mochi balls than Brandon at first. After Brandon had eaten 19 of his mochi balls, Nora had 5 times as many mochi balls as Brandon. How many mochi balls did Nora and Brandon have in total at first?

Brandon |
Total |
| Before |
1 u + 19 + 29 |
1 u + 19 |
6 u + 19 |
| Change |
|
- 19 |
|
| After |
5 u |
1 u |

The number of mochi balls that Nora had at first remains unchanged.
5 u = 1 u + 19 + 29
5 u - 1 u = 48
4 u = 48
1 u = 48 ÷ 4 = 12
Number of mochi balls that they had at first
= 6 u + 19
= 6 x 12 + 19
= 72 + 19
= 91
Answer(s): 91
