Ali takes a full-time position as a makeup artist in Atlanta. Her starting salary is $29,000. Her taxes are 28%. What is her net
malfutka [58]

Answer:

  d.  $1,740

Step-by-step explanation:

The annual after-tax salary is found by subtracting the tax from the salary. The tax is found by multiplying the tax rate by the salary. The monthly after-tax income is 1/12 of the annual after-tax income.

__

<h3>steps</h3>

  annual tax = 0.28 × $29,000 = $8,120

  annual take-home pay = $29,000 -8,120 = $20,880

  monthly take-home pay = annual pay / months per year

  = $20,880 / 12 = $1,740 . . . . net monthly income

_____

<em>Additional comment</em>

The net pay will be (1 - 0.28) = 0.72 times the nominal salary. The monthly pay will be 1/12 of the annual pay. These combined factors give a monthly net pay of (0.72)(1/12) = 0.06 times the annual pay.

  0.06 × $29000 = 6×$290 = $1740

Noam solved the equation for k using the following calculations.
goldfiish [28.3K]

Answer:

3) He made a computation error when he added 10.35+7.6

Step-by-step explanation:

Steps to add decimals:

1)Write down the numbers, one under the other, with the decimal points lined up

2) Put in zeros so the numbers have the same length

3) Then add using column addition, remembering to put the decimal point in the answer

Applying the above steps:

line the decimals up             10.35

                                                7.6

Putting zero to get same length

                                              10.35

                                                7.60

Addition:

                                               10.35

                                               +7.60

                                           ......................

                                               17.95

Now we can see that, there is error when he added 10.35 + 7.6

16 is 80% of what number
RSB [31]

Answer:

20

Step-by-step explanation:

This reads mathematically exactly how it is stated in words.  The word "is" means =, the word "of" means multiply, and "what number" is x.  Therefore, the equation from that looks like this:  16 = .80x.  Don't forget that you cannot use a percent in an equation without first changing it to its decimal equivalency.  Solve that for x by dividing both sides by .80 to get that x = 20

AlekseyPX

Answer:

First year would be 9180 and the second year would be 9363.6

Step-by-step explanation:

I just take the interest 2% make it a decimal .02 and times that by 9000 which gives you 180 then just add that to the 9000 for the first year and then for the second take 9180 times .02 which gives you 183.6 and just add that too 9180 to get 9363.6
