Answer:

see below

Step-by-step explanation:

In addition to the exponent rule ...

(a^b)^c = a^(bc)

it is helpful to know the first few powers of some small integers.

5^3 = 125

9^2 = 81

4^3 = 64

2^6 = 64

125^3 = (5^3)^3 = 5^(3·3) = 5^9
81^7 = (9^2)^7 = 9^(2·7) = 9^14
(1/64)^3 = ((1/4)^3)^3 = (1/4)^(3·3) = (1/4)^9
(1/64)^3 = ((1/2)^6)^3 = (1/2)^(6·3) = (1/2)^18

Chuck has a gross pay of $815.70. By how much will Chuck’s gross pay be reduced if he has the following items withheld? federal

tangare [24]

Chuck has a gross pay of $815.70. His gross pay will be reduced by:

Federal tax of $56;
Social Security tax that is 6.2% of his gross pay;
Medicare tax that is 1.45% of his gross pay;
State tax that is 19% of his federal tax.

Let's count:

1. gross pay of $815.70 - 100%,

Social Security tax of $x - 6.2%.

Then

$\dfrac{815.70}{x}=\dfrac{100}{6.2} ,\\ \\815.70\cdot 6.2=x\cdot 100,\\ \\x=\dfrac{815.70\cdot 6.2}{100} =50.5734.$

2. gross pay of $815.70 - 100%,

Medicare tax of $y - 1.45%.

Then

$\dfrac{815.70}{y}=\dfrac{100}{1.45} ,\\ \\815.70\cdot 1.45=y\cdot 100,\\ \\y=\dfrac{815.70\cdot 1.45}{100} =11.82765.$

3. Federal tax of $56 - 100%,

State tax $z - 19%.

Then

$\dfrac{56}{z}=\dfrac{100}{19} ,\\ \\56\cdot 19=z\cdot 100,\\ \\z=\dfrac{56\cdot 19}{100} =10.64.$

4. Chuck’s gross pay will be reduced by

$\$56+\$50.5734+\$11.82765+\$10.64=\$129.04105\approx \$129.04.$

Yes he is correct, 100% would be 10 hours again, so 110% would add the extra hour to make it 11 hours
