Question 1124145: Previous question was not written correctly. Correct question should read Suppose that the cost function for the production of a particular item is given by the function C(x)=2x second power -320x + 12,020, where x represents the number of items. How items should be produced to minimize the cost? Explain your answer.

The cost will be minimized for C'%28x%29+=+0
or +dC%2Fdx+=+0
if C%28x%29=2x%5E2+-320x+%2B+12020
dC%2Fdx+=+4x+-+320+=+0
4x+=+320+
This gives x+=+80
