Answer:
7.69%
Explanation:
The official unemployment rate includes people who do not have a job but are able to take a job and are currently seeking one.
People with part time jobs are considered employed.
Littleville has 1,000 residents, 600 are employed = 400 do not work but how many are considered unemployed:
400 - 240 (under age 16) - 10 (institutionalized) - 100 (are not looking for work, including students and homemakers) = 50 unemployed
Littleville's unemployment rate = number of unemployed / total labor force = 50 / (600 + 50) = 50 / 650 = 7.69%
