Answer:
The answer is b ($9.74)
Step-by-step explanation:
I got it right (:
the answer for this is 20.8558
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

2. gross pay of $815.70 - 100%,
Medicare tax of $y - 1.45%.
Then

3. Federal tax of $56 - 100%,
State tax $z - 19%.
Then

4. Chuck’s gross pay will be reduced by

-7 and 8 are the solutions to the given equation system.
Therefore, the maximum distance between the y values of the two equations must lie exactly between their points of intersection. That is on x value:
x = (-7 + 8)/2 = 0.5
The maximum distance is:
y = 0.5 + 56 = 56.5
y = 0.5² = 0.25
56.5 - 0.25 = 56.25 units
Let's call the lengths of our two types of sides <em />

and

.
The two sides will that our 1.3 inches bigger than the third side will be have length x, and the length of the other side will be known as y. Thus,

.
Considering this, we can add our sides together and set this value equal to 8, given the information in the problem:

Now, let's solve for y.



Now, we are not done yet. We must determine the true lengths of all of our sides. Using the equation we found earlier, the length of the two bigger sides is

inches and the length of our smaller side is simply

inches.
To verify, we can add these sides together and check that they equal 8:
3.1 + 3.1 + 1.8 = 8 ✔
