Question

In a newspaper,it was reported that the number of yearly robberies in springfield in 2011 was 240, and then went up by 5% in 2012.How many robberies were there in springfield in 2012?

Answer 1

Answer:

There were 252 robberies in 2012.

Step-by-step explanation:

Number of robberies in 2011 = 240

5% Increase =

$5/100*240=12$

Therefore, new number of robberies in 2012 =

$240+12=252$.

To confirm this figure, we use the formula,

% increase = Increase / Original number * 100

Increase= 12

Original number= 240

Therefore,

12 / 240*100 = 5

This confirms that, indeed, there was a 5% increase in 2012.
