A Better Mousetrap (Posted on 2004-01-20) Difficulty: 4 of 5
The following question was asked on a math test:
If 6 cats kill 6 rats in 6 minutes, how many will be needed to kill 100 rats in 50 minutes?

Ryan answered 12, Stefanie said 13, and Tom put down 14 for his answer. After looking at their work, the teacher decided to give all three students credit.

What were the arguments that each student made?

All the past solutions will lead to 12 as answer. Still trying to understand Stefanie's & Tom's logic
