Question

I’ve tried 32 and 140 it was incorrect how do i solve this?

Answer 1

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}`

if it went down by 8%, it can be represented as a subtraction

`1-0.08`

then, multiply by the number reported in 2011

`\begin{gathered} 175\cdot(1-0.08) \\ 175\cdot0.92 \\ 161 \end{gathered}`

There were 161 robberies in 2012.
