A company uses the formula C(x)= 0.02x^2-3.4x+150 to model the unit cost in dollars for producing x stabilzer bars. For what number of bars is the unit cost at its minimum? What is the unit cost at that level of production?
C=0.02[X^2-170X]+150=0.02[X^2-2(X)(85)+85^2-85^2]+150
C=0.02[(X-85)^2]-0.02*85^2+150
C=0.02(X-85)^2+5.5
HENCE AT X=85 , C IS MINIMUM
