Answer: 30.1%
Step-by-step explanation:
The unemployment rate includes those who do not have employment but are actively looking for employment not those who do not have a job and are not looking.
The rate is also based on the Labor force which is the portion of the population that is able and willing to work. Retirees are not included in this measure. Those who are not looking are not willing.
Labor Force = 50 full-time + 15 part-time + 28 unemployed
= 93 people
Unemployment rate:
= 28 / 93 * 100
= 30.1%
