PART 5

 1) it not fair at all.
 2) it dose not seem fair and just
 3) this isn't fair because the homeless man stole $100 to live and he was sent to jail for 15 years. on the other hand the CEO was sent to jail for only 40 MONTHS for $3 billion fraud.
 4) if i were the judge i would have sent the CEO for 25 years of fraud. for the homeless man i wouldn't send him to jail i would sentence him not guilty and let him free.


bonus question

 
  question: how tall is the trees.
answer: i guessed that this boy is about 12 years old. So i did some research and i found that an average 12 year old boy is about 5'3 so i did some calculations. if you stacked the boy in front of the trees there would be 3 boy stacked on top of each other.

5.3x3=15.9. so the trees must be 15.9 ft tall.
