Answer:
Option c.
Step-by-step explanation:
It is given that the piecewise function represents the Social Security taxes for 2009.
We need to find Rachel's security tax if she earned $102,000 in 2009.
Since 102,000 lies in 
, therefore
Put x=102000.
So, the Social Security tax is $6324.
Therefore, the correct option is c.
The answer is C,
We use the 'more than or equal sign' as the consultant needs to make at least $600 - so exactly $600 or more than $600
Let there be x quarts of the 20% salt solution, and (25 - x) quarts of the 80% salt solution.
Then the total amount of salt in the 20% portion would be 0.2x, while that from the 80% portion would be (0.8)(25 - x). This would have to total up to (0.44)(25) in the final solution, so the equation is:
0.2x + 0.8(25 - x) = (0.44)(25)
-0.6x + 20 = 11
x = 15 quarts of the 20% salt solution
25 - x = 10 quarts of the 80% salt solution
Answer:
- A-B=7x-3x+10-4x²-66+4
- 4x-52-4x²
