If the cost function for producing x bars is
, then to find the cost per bar, you must divide this by x.
Cost per bar=
If you are in a calculus class (probably Calculus for Businees Majors or Concepts of Calculus!), then you take the derivative of this.
Set derivative = zero, and solve for x:
Multiply both sides by the LCD
Divide by .2
Square root both sides, where x>0:
x= sqrt(750)= 27.386
Unit cost (when x= 27 bars) = 7.55555. . .
