Tom and Harry shared equally a bunch of grapes. After Tom had eaten 31 of his grapes and Harry had eaten 16 of his, Harry had 6 times as many grapes left as Tom. How many grapes had each of them at first?
| |
Tom |
Harry |
| Before |
1 u + 31 |
6 u + 16 |
| Change |
- 31 |
- 16 |
| After |
1 u |
6 u |
Number of grapes each had at first was the same.
6 u + 16 = 1 u + 31
6 u - 1 u = 31 - 16
5 u = 15
1 u = 15 ÷ 5 = 3
Number of grapes that they had each at first
= 1 u + 31
= 3 + 31
= 34
Answer(s): 34
