Answer:
the labor force participation rate is 80%
Step-by-step explanation:
The computation of the labor force participation rate is given below:
Labor force participation rate = labor force ÷ working-age population × 100
= 400,000 ÷ 500,000 × 100
= 4 ÷ 5 × 100
= 80%
hence, the labor force participation rate is 80%
