Question 60402: 64. Minimizing cost. A company uses the formula C(x) = 0.02x^2 � 3.4x + 150 to model the unit cost in dollars for producing x stabilizer bars. For what number of bars id the unit cost at its minimum? What is the unit cost at level of production?

The minimum will be on the Line of Symmetry at the Turning Point.
The LOS can be found using LOS =-b/2a with a being the x^2 coefficient and b being the x coefficient
For the equation C(x) = 0.02x^2 � 3.4x + 150
the LOS = 3.4/(2*0.02)
= 3.4/0.04
= 85
Substitute x = 85 into the Cost equation to find the cost of producing that many bars

The cost per item is found by dividing the cost by the number of items
= $0.064
