Part 4

Part 5
1. Does this seem fair?
 No it isn't fair.
2.With what you know about proportion look and read what is in the image above.  Does it seem just and fair? 
100 dollars for 15 years? Too much. It should be about few thousand or tens of thousands to be 15 years. So no, it does not seem just or fair.

3.Why have you made this choice? 

Because 15 years is way too much for 100 dollars, and that guy was homeless now I feel bad for him.

4.What would you have done if you were the judge?

I would let him in jail for a week or so, because he only stole 100 dollars, and he gave it back and admit he stole it.
