Question 16537: I am not sure where to ask this. This is not a quadratic equation, but here is the problem.
A company uses the function C(x)= 0.2X^2-3.4x+150 to model the unit cost in dollars for producing x bars. For what number of bars is the unit cost at its minimum? What is the unit cost at that level of production?
I guess I want to solve for C but I don't see two equations here. By using the brute force method, I get the lowest cost to be at 27 bars and a cost of 7.555555555 repeating.
