We will solve as follows:
First, we determine the 5.9% of 13002, that is:
[tex]x=\frac{13002\cdot5.9}{100}\Rightarrow x=767.118[/tex][tex]\Rightarrow x\approx767[/tex]Now, we calculate the approximate number of employees on 2006:
[tex]E_{2006}\approx13002-767\Rightarrow E_{2006}\approx12235[/tex]So, the number of employees on 2006 will be approximately 12235.
