We can use a rule of three to solve the exercise.
[tex]\begin{gathered} 175\rightarrow100\% \\ x\rightarrow92\% \\ \text{ Because }100\%-8\%=92\% \end{gathered}[/tex][tex]\begin{gathered} x=\frac{92\%\cdot175}{100\%} \\ x=\frac{92\cdot175}{100} \\ x=\frac{16100}{100} \\ x=161 \end{gathered}[/tex]
Therefore, there were 161 robberies in Springfield in 2012.
