If the workers in both cities earn the averages shown in the chart, how much greater is the overall weekly earnings average in City D than in City C?
A. $ 55.00
B. $ 57.50
C. $ 275.00
D. $ 5500.00
E. $ 5750.00
From above fig,
weekly earnings average in City D greater than in City C =
{( 1200 * 0.45) + (750 * 0.25) +( 675 * 0.25) + (500 * 0.05)} - {( 1200 * 0.35) + (750 * 0.3) +( 675 * 0.25) + (500 * 0.1)} = 921.25 - 863.75 = $57.5
