Tanya’s gross pay this pay period is $2,100. She is expecting $300 to come out for taxes and insurance. What should her net pay be on her paycheck?

Answers

Answer:

1800

Step-by-step explanation:

if 300 is all that is being subtracted from her gross pay then it should just be 2100-300=netpay

After deducting the tax and insurance from the gross pay, the net pay that will be on Tanya's paycheck is $1,800.

Given parameters:

Tanya's gross pay = $ 2,100

Estimated amount for tax and insurance = $300

To find:

the net pay on her paycheck

Tanya's net pay after deducting the tax and insurance is calculated as;

The net pay = Gross pay - tax and insurance

The net pay = $ 2,100 - $300The net pay = $1,800

Thus, the net pay that will appear on Tanya's paycheck is $1,800.

Answers

This question is incomplete, the complete question is;

Vic bought a new plasma TV for ​$2400. He made a down payment of ​$200 and then financed the balance through the store.​ Unfortunately, he was unable to make the first monthly payment and now pays 6​% interest per month on the balance​ (while he watches his​ TV).

What is Vic's Monthly interest payment ( Assume interest rates are 1/12 of annual interest rates)

Answer: Vic's Monthly interest payment is $132

Step-by-step explanation:

Given that;

Purchase cost of plasma Tv = $2400

down payment made = $200

so,

Balance financing from store = $2400 - $200 = $2,200

also given that Interest rate is 6% per month6

Now Monthly interest payment will be;

⇒ financing amount × interest rate

⇒ 2200 × (6/100) = 132

Therefore, Vic's Monthly interest payment is $132

[tex]Each\ Part = 4.29\ ft[/tex]

Step-by-step explanation:

Given

[tex]Length = 30\ ft[/tex]

[tex]Parts = 7[/tex]

Required

Determine the length of each part

This is calculated as:

[tex]Each\ Part = \frac{Length}{Parts}[/tex]

[tex]Each\ Part = \frac{30\ ft}{7}[/tex]

[tex]Each\ Part = \frac{30}{7}\ ft[/tex]

Hence, the length of each part is approximately 4.29ft
