The net salary after all deductions will be $66,129 and can be calculated by subtraction of gross salary from all deductions thus option (d) is correct.
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects.
In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.
The group's total number of items decreases or becomes lower when we subtract from it.
Gross income = $85,463
Deductions are,
Income will be $896
Exemptions is 2 x $3,650
Charitable donations is $2,145
Exemptions is 2 x $3,650 expenses is $3,473
Add all above the deduction to find out the total deduction,
$896 + $2,145 + $3,473 + 2 x $3,650 = $13,814
Thus, net income will be as by subtraction,
$85,463 - $13,814 = $66,129
Hence "The net salary after all deductions will be $66,129 and can be calculated by subtraction of gross salary from all deductions".

In a certain clothing store, 3 shirts and 5 ties cost $60, and 2 shirts and 3 ties cost $39. What is the cost of each shirt? If s = the cost of a shirt and t = the cost of a tie, which system of equations represents the problem? 3s 5t = 60 and 2s 3t = 39 s t = 60 and 5s 8t = 99 3t 5s = 60 and 2t 3s = 39.
Answer:
ties cost $3
shirts cost $15
Step-by-step explanation:
s=shirts
t = ties
3 shirts and 5 ties cost $60:
3s+5t=60
2 shirts and 3 ties cost $39:
2s+3t=39
−2(3s+5t=60)
3(2s+3t=39)
−6s−10t=−120
6s+9t=117
add equations together:
−t = −3
t = 3
so ties cost $3, use either of the original equations to solve the price of shirts:
2s+3⋅(3)=392
s+9=392s=30
s=15
so shirts cost $15
Answer:
3s + 5t = 60 and 2s + 3t = 39

If f(1) = 0, what are all the roots of the function f (x) = x cubed 3 x squared minus x minus 3? Use the Remainder Theorem.
Remainder theorem tells about the remainder of division of a polynomial with x - a. The roots of given function are: 1, -1, -3
What is remainder theorem for polynomials?If there is a polynomial p(x), and a constant number 'a', then
[tex]\dfrac{p(x)}{(x-a)} = g(x) + p(a)[/tex]
where g(x) is a factor of p(x)
For the given case, we've got:
[tex]f(x) = x^3 + 3x^2 -x - 3[/tex]
and
f(1) = 0
Thus, for a = 1, from remainder theorem, we get:
[tex]\dfrac{p(x)}{(x-a)} = g(x) + p(a)\\\\\dfrac{f(x)}{(x-1)} = g(x) + f(1)\\\\\dfrac{x^3 + 3x^2 - x - 3}{(x-1)} = g(x) + 0\\\\ \dfrac{x^2(x+3) -1(x+3)}{x-1} = \dfrac{(x^2-1)(x+3)}{(x-1)} = g(x)\\\\(x+1)(x+3) = g(x)[/tex]
Thus, the other factor of f(x) is g(x) = (x+1)(x+3)
And we have:
[tex]\dfrac{f(x)}{x-1} = g(x)\\\\f(x) = (x+1)(x+3)(x-1)[/tex]
Putting it equal to 0, we get:
[tex]f(x) = 0\\(x+1)(x+3)(x-1) = 0\\x = 1, -1, -3[/tex]
Thus,
The roots of given function are: 1, -1, -3

the price paid for a 83.50 dollar chair with an 8 percent sales tax
Answer:
$90.18 dollars
Step-by-step explanation:
Given the following question:
Original cost = $83.50
Sales tax = 8%
In order to find the price paid for the chair, we find 8 percent of the original price. Then we add that number to the $83.50 for the chair and then we will have our answer.
[tex]\frac{8\times83.5}{100} =8\times83.5=668\div100=6.68[/tex]
Sales tax of the chair is $6.68.

Is Tom's ladder safe to use?
Answer:
Tom should use a ladder that is smaller or at the the same height of the window frame. Here it says that he is using a ladder that is taller than the window frame, and this can be very uncomfortable for the person who is using the ladder, so it would be recommendable for Tom to use a smaller ladder, probably a ladder that is only a few inches smaller or taller than the window frame. Using a ladder that is like this should be safe to use.
