Question: what was the percentage change in capital expenditures for property , plant and equipment from 2008 to 2009? (in percentage)

Solution:
def solution():
    # Define variables name and value
    capital_expenditures_2009 = 852
    capital_expenditures_2008 = 926

    # Calculate the percentage change in capital expenditures
    difference = capital_expenditures_2009 - capital_expenditures_2008
    percentage_change = (difference / capital_expenditures_2008) * 100
    
    return percentage_change
Answer: -7.991360691144708
