Warren and Tom shared equally a bunch of grapes. After Warren had eaten 33 of his grapes and Tom had eaten 12 of his, Tom had 4 times as many grapes left as Warren. How many grapes had each of them at first?
| |
Warren |
Tom |
| Before |
1 u + 33 |
4 u + 12 |
| Change |
- 33 |
- 12 |
| After |
1 u |
4 u |
Number of grapes each had at first was the same.
4 u + 12 = 1 u + 33
4 u - 1 u = 33 - 12
3 u = 21
1 u = 21 ÷ 3 = 7
Number of grapes that they had each at first
= 1 u + 33
= 7 + 33
= 40
Answer(s): 40
