The cost function is given by C(x) = 2x 2− 3x + 5, where x is the number of items produced. For what value of x is the AVERAGE cost function minimized?

The average cost is minimized for x=1.58.

Step-by-step explanation:

The cost function is C(x) = 2x 2− 3x + 5, where x is the number of items produced.

The average cost is C(x)/x, that is the total cost divided by the units produced.

Then the average cost function A(x) becomes:

To optimize this function, we derive and equal to zero:

The average cost is minimized for x=1.58.
