stepan [7]

Answer: labor force participation rate  =60%

unemployment rate = 6.67%

Step-by-step explanation:

The labor force participation rate is computed as

\text{labor force participation rate}=\dfrac{\text{Total employed persons}}{\text{Total population}}

i.e. \text{labor force participation rate}= \dfrac{72000}{120000}

= 0.6\ or\ 60 \%

The unemployment rate is computed as:

\text{unemployment rate}=\dfrac{\text{Number of personsdon't have jobs }}{\text{Total population}}\\\\\text{unemployment rate}=\dfrac{8000}{120000}\\\\\text{unemployment rate}=0.0667\ or\ 6.67\%

Hence, labor force participation rate  =60%

unemployment rate = 6.67%

The original price of a pair of shoes is $42. The sale price is 20% off the original price. What is the amount off the original
GREYUIT [131]

Answer:

a) What is the amount off the original price?

= $8.4

b) What is the new price for the pair of shoes?

= $33.6

Step-by-step explanation:

a) What is the amount off the original price?

We are told that:

The sale price is 20% off the original price.

Original price = $42

Hence:

$42 × 20%

$42 × 20/100

= $8.4

b) What is the new price for the pair of shoes?

The new price =

0riginal price - Amount off the original price

= $42 - $8.4

= $33.6

The original price = $33.6
