Asher and Zeph shared equally a bunch of grapes. After Asher had eaten 31 of his grapes and Zeph had eaten 19 of his, Zeph had 3 times as many grapes left as Asher. How many grapes had each of them at first?
| |
Asher |
Zeph |
| Before |
1 u + 31 |
3 u + 19 |
| Change |
- 31 |
- 19 |
| After |
1 u |
3 u |
Number of grapes each had at first was the same.
3 u + 19 = 1 u + 31
3 u - 1 u = 31 - 19
2 u = 12
1 u = 12 ÷ 2 = 6
Number of grapes that they had each at first
= 1 u + 31
= 6 + 31
= 37
Answer(s): 37
