Question

In a newspaper, it was reported that yearly robberies in Springfield were up 25% to 265 in 2013 from 2012. How many robberies were there in Springfield in 2012?

Answer 1

234

Step-by-step explanation:(\text{\# robberies in }2012)(1+r)=\text{\# robberies in }2013

(# robberies in 2012)(1+r)=# robberies in 2013

x(1+0.5)=351

x(1+0.5)=351

x(1.5)=351

x(1.5)=351

\frac{x(1.5)}{1.5}=\frac{351}{1.5}

1.5

x(1.5) = 1.5 351

​

x=234

x=234

\text{There were 234 robberies in 2012}

There were 234 robberies in 2012
