The average number of hours worked per week drop from 2009 to 2010 dropped by 1.16%
How to determine the percentage change?
The average work weeks are given as:
Year 2009 = 43 hours
Year 2010 = 42 hours 30 minutes
Rewrite as:
Year 2010 = 42.5 hours
The percentage change is then calculated as:
Percentage change= (Final - Initial)/Initial * 100%
So, we have:
Percentage change= (42.5 - 43)/43* 100%
Evaluate
Percentage change= -1.16%
Hence, the average number of hours worked per week drop from 2009 to 2010 dropped by 1.16%
