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
It's given in the question,
- Bianca works as a content writer for $10 per hour.
- She works as a library assistant for $14 per hour.
She worked for a combined total of 75 hours for both the jobs this month.
Let c be the number of hours Bianca worked as a content writer.
Her earning for this month as a content writer = $10c
Her working hours as library assistant this month = (75 - c) hours
Therefore, her earning as a library assistant for the month = $14(75 - c)
By adding the earnings as a library assistant and a content writer for the month = $10c + $14(75 - c)
= (10c - 14c) + 1450
= $(9c + 1050)
Therefore, expression for the combined total amount she earned this month will be $(9c + 1050).
