1. Does this seem fair? 
No, I dont think it is fair.

2. With what you know about proportion look and read what is in the image above.  Does it seem just and fair?
No, I still don't it's fair. 

3. Why have you made this choice?
Because the homeless guy got sentenced for 15 years in jail for just stealing $100, but then turned his self in the next for being guilty. As when the other guy gets sentenced for only 4o months when he stole $3 billion. 

4.What would you have done if you were the judge?
If I were the judge, I would've sentenced the homeless guy for only 1-2 months. As for the other guy I would've sentenced him for more than 15 years in jail. Or I would reduced if he returned the money back which he probably didn't.

Bonus question:


How much taller is the trees from the guy walking?
An average kid that is about 14 years old is about 5'6 ft. So, 3 kids his height stacked up on each other will equal the height of the tree. When I figured that out, I multiplied 5'6 by 3 and got the answer of 16'8 ft. tall. So, the trees are about 11.2 ft. taller than the kid walking.
