Question 98941: I have no idea how to solve this problem, someone please help me! The problem is:
Suppose the cost function for the production of a particular item is given by the equation +C%28x%29=2x%5E2-320x%2B12920+, where x represents the number of items. How many items should be produced to minimize the cost?

You can put this solution on YOUR website!
a=2, b=-320, c=12920
minimum at x=-b/2a=320/2*2=320/4=80 items should be produced
