In order to find how many robberies there were in Springfield in 2012, start writing the percentages as decimals
![\begin{gathered} 100\%=1 \\ 8\%=0.08 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/rnkds5x90k9gxhiw1e9njsfhpxy12cyg74.png)
if it went down by 8%, it can be represented as a subtraction
![1-0.08](https://img.qammunity.org/2023/formulas/mathematics/college/4c2xu86pdx38gxcrowigojs504vuqfj3ol.png)
then, multiply by the number reported in 2011
![\begin{gathered} 175\cdot(1-0.08) \\ 175\cdot0.92 \\ 161 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/dhvml6jousnucr5iyn0j16o6pvh4p5nf9k.png)
