Picture an economy with 100,000 workers in its labor force. The unemployment rate is simply the number of unemployed workers divided by the number of workers in the labor force. At the beginning of January, the unemployment rate is 4.76%, so 4,760 people in the labor force are unemployed. Suppose that in January, 10% of the workers who were unemployed at the beginning of the month start new jobs. This means that ________ people leave the unemployment category in January....

A) A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 26 weeks.
