You have that:
- Her contribution from her salary <span>to her 401(k) plan, </span>is: 12%.
- Her annual salary is: $55,700.
Then, to solve this problem and calculate her pretax income, you must following the steps below:
1. You must calculate the amount that Violet contributed to her 401(k) plan. So, you have:
12%/100=0.12
($55,700x0.12)=$6,684
2. Now, you must subtract her annual pay ($55,700) by the amount obtained ($6,684), as below:
Pretax income= $55,700-$6,684
<span> Pretax income=$49,016
</span><span>
What is her pretax income?
The answer is: Her pretax income is </span>$49,016
Answer:
I guess that you want to find the profit:
We have two equations:
the cost equation:
C(x) = -0.1*x^2 + 100.
And the selling equation, that is a vertical stretch of the cost equation by a factor of 1.4:
S(x) = 1.4*C(x) = 1.4*( -0.1*x^2 + 100.) = -0.14*x^2 + 140
Now, whit those two equations we can find the profit equation, that is defined as the difference between the selling price, and the cost:
P(x) = S(x) - C(x) = 1.4*C(x) - C(x) = (1.4 - 1)*C(x) = 0.4*C(x).
Then the profit is 0.4 times the initial cost.
P(x) = 0.4*( -0.1*x^2 + 100.) = -0.04*x^2 + 40
