Suppose a firm has the following total cost function:

 

                   TC = 1000 + 240Q - 4Q² + (1/3)Q³

 

    (a) Write the equations for:

         i) Average fixed cost:

 

        ii) Average variable cost:

    

        iii) Marginal cost:

 

    (b) Determine the output level and value of MC at which MC is minimized.

 

   (c) At what level of output does the diminishing returns set in?

 

  (d)  Determine the output level, and values of AVC and MC at which AVC is minimized.
