Answer:
the total labor force for the first part of the question = 75,000 and 5,000 are unemployed, therefore, the unemployment rate = 6.67%
if 5,000 more people enter the labor force, then the total labor force = 80,000 people. Out of the total, 8,000 are unemployed, therefore, total unemployment = 8,000 / 80,000 = 10%
on the other hand, the employment rate = total employed / total population will also increase. The original employment rate = 70,000 / 100,000 = 70%
Then as 2,000 more people were employed, the employment rate increased to 72,000 / 100,000 = 72%
