Norma-Jean [14]

Answer:

54minutes

Step-by-step explanation:

Let the time taken to clean up be t

Let the number of people cleaning be n

If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;

t = k/n

k is the constant of proportionality

If 3 people work together to clean, and took them 90 minutes, this means

at t = 90, n=3

Substitute

90 = k/3

k = 3×90

k = 270

To et the time it will take 5people to clean, the will say;

t =k/n

t =270/5

t = 54 minutes

Hence it will take 5 people 54minues to clean

Raquel has gross pay of $732 and federal tax withholdings of $62. Determine Raquel’s net pay if she has the additional items wit
IceJOKER [234]

Answer:

The net pay of the Raquel be $601 .

Step-by-step explanation:

As given

Raquel has gross pay of $732 and federal tax withholdings of $62.

Social Security tax that is 6.2% of her gross pay .

6.2% is written in the decimal form.

= \frac{6.2}{100}

= 0.062

Social Security tax = 0.062 × Gross pay

                              = 0.062 × 732

                               = $ 45.38 (Approx)

As given

Medicare tax that is 1.45% of her gross pay .

1.45% is written in the decimal form.

= \frac{1.45}{100}

= 0.0145

Medicare Tax = 0.0145 × Gross pay

                       = 0.0145 × 732

                       = $ 10.6 (Approx)

As given

State tax that is 21% of her federal tax.

21% is written in the decimal form.

= \frac{21}{100}

= 0.21

State tax = 0.21 × Federal tax

              = 0.21 × 62

              = $13.02

Total amount of the tax = Federal tax + Social Security tax + Medicare Tax + State tax

Putting all the values in the above

                                      = $62 + $45.38 +$10.6 + $13.02

                                      = $ 131

Raquel’s net pay = Gross pay - Total amount of taxes

                             = $732 - $131

                             = $ 601

Therefore the net pay of the Raquel be $601 .
