Answer:
B. 7.7
Step-by-step explanation:
Given that
Civilian employed = 180 million
Civilian unemployed = 15 million
Total adult population = 280 million
Recall that
Unemployment rate = unemployed/total labour force × 100
Also,
Total labour force = number of employed + number of unemployed
Thus,
Total labour force = 180 + 15
= 195 million
Therefore,
Unemployment rate = 15/195 × 100
= 0.0769 × 100
= 7.69%
= 7.7%
The unemployment rate from the given data is 7.7%
