A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the numb
ArbitrLikvidat [17]

Answer:

  $9327

Step-by-step explanation:

Apparently, the cost function is supposed to be ...

  C(x) = 0.4x^2 -112x +17167

This can be rewritten to vertex form as ...

  C(x) = 0.4(x^2 -280) +17167

  C(x) = 0.4(x -140)^2 +17167 -0.4(19600)

  C(x) = 0.4(x -140)^2 +9327

The vertex of the cost function is ...

  (x, C(x)) = (140, 9327)

The minimum unit cost is $9327.

_____

<em>Comment on the question</em>

You found the number of units that result in minimum cost (140 units), but you have to evaluate C(140) to find the minimum unit cost.
