Marginal Cost

The additional cost incurred by producing one more unit of a product.

Average Cost

The total cost of production divided by the number of units produced.

Fixed Cost

A cost that remains constant irrespective of the level of production.

Study Notes

Marginal Cost Function

  • Marginal cost (MC) is given by the function: MC = 2(2x + 9)-1/2
  • x represents the number of units produced.

Average Cost Calculation

  • Find the total cost (TC) by integrating the marginal cost function.
  • The fixed cost (FC) is Rs 4.
  • Calculate the total cost for 8 units of production.
  • Average cost (AC) = (TC + FC)/x
  • Substitute x = 8 into the formulas to find the average cost for 8 units of production.
