Hey im confused on how to solve this. Can Anyone help me?

The minimum unit cost is $9374.

Step-by-step explanation:

The unit cost C for making x engines is given by the quadratic function:

We want to determine the minimum unit cost.

Since this is a quadratic function with a positive leading coefficient, the minimum value will be its vertex. The vertex of a quadratic can be found using the following formulas:

In this case, a = 0.3, b = -162, and c = 31244.

Find the x-coordinate of the vertex:

In other words, in order to achieve the minimum cost, only 270 engines must be made.

Then to find the minimum cost, substitute the value back into the function. So:

The minimum unit cost is $9374.

make sure you have version 2.50

try looking in the very back of the book : )
