<span>$15.16, FICA tax
</span><span>$29.33, income tax
</span><span>2% state tax = 215 x 0.02=$4.3
</span><span>1% city tax = 215 x 0.01 = $2.15
</span><span>3% retirement fund = 215 x 0.03 = $6.45
</span>
$15.16 + $29.33 + $4.3 + $2.15 +  $6.45 = $57.39

$215 -$57.39 =$157.61

net income = $157.61

How do you find the sale's price for a sneaker that is normally sold at $150 but is now being sold at a 23% discount?
Alex
You multiply $150 times 23%
or .23
this equals 34.5 which is the amount you will be taking off (the discount)
so then you subtract 150-34.5 which equals $115.50

What is the completely factor form of x4+8x2-9
Mademuasel [1]
It takes some trial and error

To find the factored form, you know that the format will look like

 (x^n +/- a) (x^n +/- b)  

Since the expanded form has x^4, the first part of each expression in parentheses will be x^2  because x^2 * x^2 will give you x^4

Then you have to figure out, how will you get -9 in the expanded form? The "a" and "b" parts of each expression will have to multiply to equal -9.

Factors of -9 will be -3*3 or -1*9 or -9*1

Also, consider the 8x^2 part - as it relates to finding the factors of 9. The parts of the expression that result in  8x^2  in the expanded form ...

a*x^2 + b*x^2 = 8x^2

If you think about this, you know the a and b will  = -1 and 9 because you also have to add the expressions with x^2 to get 8x^2, and 3 and 3 would not give you the 8x^2 and neither would nor would -9 and 1.

Final factored form is

(x^2 - 1) (x^2 + 9)
