A company uses the formula C(x) = 0.02x^2 � 3.4x + 150 to model the unit cost in dollars for producing stabilizer bars. For what number of bars is the unit cost at its minimum? What is the unit cost at that level of production?
This is a quadratic equation, it's minimum is it's vertex. When a quadratice equation is in standard form:, the x coordinate of the vertex is found with the formula:
a=.02, b=-3.4, and c=150

This is the number of bars in which the unit cost is at its minimum.

The minimum cost per unit is $5.50
Happy Calculating!!!
