Answer: There were 220 robberies in Springfield in 2010
Step-by-step explanation: If the robberies were reported to be down 20% and the new figure is 176, it simply means the figure 176 depicts 80% (or 0.8) of the figure from year 2010.
We shall take the figure in year 2010 as x, which is 100% (or 1.0) and year 2011 is 176 which is 80% (or 0.8). What we now have is;
176/x = 0.8
176/x = 4/5
By cross multiplication we now have;
(176 x 5)/4 = x
880/4 = x
220 = x
Therefore, there were 220 robberies in Springfield in 2010
