Answer:
The percentage of people with annual incomes below the poverty line in Econville is 60%
Step-by-step explanation:
The poverty line is the level of income below which the person earning is considered as Poor.
Poverty line = $16,000
All the people earning less than $16,000 are considered as the people with annual income below the poverty line.
People below poverty line = All the people eaning below $16,000 = High school student + undergraduates + retiree
People below poverty line = 1,000 + 1,000 + 1,000 = 3,000
Total Population = 5,000
Percentage of people with annual incomes below the poverty line in Econville = ( People having income below $16,000 / Total population ) x 100 = ( 3,000 / 5,000 ) x 100 = 60%
