Question 99593: 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 is the unit cost at it's minimum? What is the unit cost at that level of production?

You can put this solution on YOUR website! 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 is the unit cost at it's minimum? What is the unit cost at that level of production?
------------------
The equation is a quadratic with a=0.02 , b=3.4 , c=150
The minimum is at x=-b/2a = -3.4/(2*0.02)= -85
------------
Comment:
The number of bars cannot be negative. Check you equation again.
