Complete question:
An aircraft factory manufactures airplane engines. The unite cost C ( the cost in dollars to make each airplane engine) depends on the number of engines made. If x is the number of engines made, then the unit cost is given by the function C(x)=0.8x^2-160x+26848. What is the minimum unit cost? not rounded
Answer: $18848
Explanation:
Since we have the function
C(x) = 0.8x²-160x+26,848
Firstly, we differentiate
C'(x) = 1.6x - 160
The minimum cost will occur where x = 100.
The vertex of a parabola (quadratic equation) occurs where X = -b/2a, in this case we have that
X = 160/(2×0.8) = 100
Therefore, we substitute x = 100 into the original equation
We have that
C(x) = 0.8(100)²-160(100)+26848
C(x) = 8000-16000+26848
C(x) = $18848

The answer is B)<span> Older persons nearing retirement and needing to know what their income will most likely be during retirement
Option D, would be wrong since without the means to have a financial planning assistant would not really be able to achieve much aside from probably saving some more money.
However, older people who are nearing retirement are probably at the top of their careers and have a lot of savings in cash, bongs, stocks and maybe even property.
It is these kinds of people who can get maximum benefit from proper financial planning.
