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
