In which year was the amount of profit was maximum?

Income = Expenditure*(1+P%) ==> Expenditure = $$\frac{Income}{1+P\%}$$.
Profit = Income - Expenditures ==> $$Income\ -\ \frac{Income}{1+P\%}=Income\times\ \left(\frac{1+P\%-1}{1+P\%}\right)=Income\times\ \left(\frac{P\%}{1+P\%}\right)$$.
This formula gives profits for all the years as:
2003 = 7.65,
2004 = 14.7
2005 = 14.36
2006 = 14
2007 = 17.87 and,
2008 = 16.66.
The year in which profit is maximum is 2007.
