Answer:

The 4th option is the correct answer

It will take  19 hours of lesson

Step-by-step explanation:

It is given that,

Ahmets rent a piano for $35 per month.

Also he earn $25 per hour giving piano lessons.

He wants to make profit $440 per month.

<u>To calculate the hours needed for getting profit $440 </u>

Let x be the total hours spending for piano lesson

So he earn $25x in one month

But the expenditure is piano rent $35 per month.

Multiple Representations Explain how to use a number line to find the
DaniilM [7]

Answer:

First, 3 units away from -7 could be, either -10 (when going to the left), or -4 (moving 3 to the right). Lastly, the opposite of the integer(s), (if opposite is meaning, if the third number is -10, then the "opposite" could be the positive number "10".? and/or the other third integer is -4, then the "opposite" could be its positive, or absolute value of the negative number, or just "4".  i.e. If given a " -4", then the absolute value of it is, +4.  Or, also can be written, |-4|, meaning, the absolute value of -4, equals +4, or 4.

Step-by-step explanation:

Draw a line straight across your paper (from left to right), then in the middle of the line, make a little mark straight up and down and label it 0 (zero).  To the right, each little mark made through the line, will be positive, and go up from zero "0" to 1, then 2, then 3, then 4, and so on... Usually making a standard size number line, mark and count up to about "10".

Next, from the middle "0", moving to the left, making small marks through the line, counting from "0", to 1, and 2 and 3 and so on, EXCEPT making all these numbers negative, until getting to "-10" on the number line.

Your annual salary is $28,460 your State personal deductions total $88 for a weekly pay period. The state tax rate is 3.6% of ta
miv72 [106K]

Answer:

First, in one year you win:

$28,460

Now yearly we can subtract:

3.6% for the taxable income

1.7% for the gross pay:

(Those apply to the complete annual salary)

3.6% + 1.7% = 5.3%

This in decimal notation is 0.053, then paying those two things we have left:

$28,460*(1 - 0.053) = $26,951.62

Now we need to subtract the union dues, which are $156 per year.

$26,951.62 - $156 = $26,795.62

Now, this is yearly, and we want to know the weekly pay.

In one year we have 365 days.

One week has 7 days.

Then in one year, we have:

365/7 = 52.14 weeks.

Then the pay per week is:

$26,795.62/52.14 = $513.92

And now, each week we must pay $88 for state personal deductions, and $67 for FIT.

Then we have:

$513.92 - $88 - $67 = $358.92

Then the net pay for each weekly pay period is: $358.92
