how is the staff salaries percentage increase from 2008 to 2009 calculated to 0.31 in module question?

I got 30.72 % as the answer which can be rounded to 31%. I just wanted to check whether you calculated the change in salary per unit basis and got the answer as 0.31 or did i make a mistake somewhere. I still marked the answer as 0.31 and got it right.
My calculation:
Percentage Change= (Change in Staff cost)*100/(Staff cost in 2008)

The 31% is indeed the rounded off answer. You answer is accurate.
