To determine

Concept Introduction:

Average Total Cost: It is also referred as the cost of a single unit, it includes the overall cost, that is the variable cost as well as the fixed cost. A firm should always maintain the price of a product above the ATC, otherwise it will result in loss for the firm. The formula for ATC is:

Here,

• AFC is the average fixed cost.
• AVC is the average variable cost.
• ATC is the average total cost.

Marginal Cost (MC): It refers to the rate by which the total cost of the produced good changes when the production increases by a single unit. As the fixed cost is constant irrespective of production, so the marginal cost depends on the variable cost only in the short run. Marginal cost is calculated as follows:

Here,

• is the marginal cost.
  
• is the change in total cost
  
• is the change in quantity.
