• Hint 1: provide your answer at least up to 2 decimal points in % term, i.e., if the answer is 23.45% (=0.2345), then enter "23.45". To get more accurate answer, try to use as many decimal points as possible in middle steps.
• Hint 2: If depreciated, then the answer should be negative number. Please put "-" (minus sign) in front of your answer.
