Tommy and Will shared equally a bunch of rambutans. After Tommy had eaten 36 of his rambutans and Will had eaten 18 of his, Will had 7 times as many rambutans left as Tommy. How many rambutans had each of them at first?
|
Tommy |
Will |
Before |
1 u + 36 |
7 u + 18 |
Change |
- 36 |
- 18 |
After |
1 u |
7 u |
Number of rambutans each had at first was the same.
7 u + 18 = 1 u + 36
7 u - 1 u = 36 - 18
6 u = 18
1 u = 18 ÷ 6 = 3
Number of rambutans that they had each at first
= 1 u + 36
= 3 + 36
= 39
Answer(s): 39
