Answer
Explanation:
Step1: Recall percent - increase formula
The percent - increase formula is $\text{Percent Increase}=\frac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\times100%$.
Step2: Calculate percent increase for Orthodontist
Old value in 2006 is $9206$, new value in 2016 is $10214$. $\text{Percent Increase}=\frac{10214 - 9206}{9206}\times100%=\frac{1008}{9206}\times100%\approx10.95%$.
Step3: Calculate percent increase for Sound engineer technician
Old value in 2006 is $16125$, new value in 2016 is $17864$. $\text{Percent Increase}=\frac{17864 - 16125}{16125}\times100%=\frac{1739}{16125}\times100%\approx10.8%$.
Step4: Calculate percent increase for Police officer
Old value in 2006 is $648982$, new value in 2016 is $719041$. $\text{Percent Increase}=\frac{719041 - 648982}{648982}\times100%=\frac{70059}{648982}\times100%\approx10.8%$.
Step5: Calculate percent increase for Editor
Old value in 2006 is $122273$, new value in 2016 is $124135$. $\text{Percent Increase}=\frac{124135 - 122273}{122273}\times100%=\frac{1862}{122273}\times100%\approx1.52%$.
