Question 118254
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 its minimum? What is the unit cost at that level of production.
-------------------
Minimum occurs when x = -b/2a = 3.4/(0.04) = 85
-------------
Unit cost at that level is C(85) = 0.02(85^2)-3.4(85)+150 = $5.50
