Answer:

$15,339

Step-by-step explanation:

C(x) = 0.5x² − 100x + 20,339

Since this is a parabola, the minimum cost is at the vertex:

x = -b / (2a)

x = -(-100) / (2 × 0.5)

x = 100

So the minimum cost is:

C(100) = 0.5(100)² − 100(100) + 20,339

C(100) = 15,339

since they are raised to the same power:

(4x * (x+7))^{1/2}\\(4x^2 + 28x)^{1/2}\\\\=\sqrt{4x^2 + 28x}
