Marginal cost = derivative of (Total cost/Quantity)

Where Total cost = fixed cost + variable cost

Marginal cost = derivative (Variable cost/Quantity) (by definition, fixed costs do not vary with quantity produced)

Average cost = Total cost/Quantity

The rate of change of average cost is equivalent to its derivative.

Thus,

AC' = derivative(Total cost/Quantity) => derivative (Variable cost/Quantity) = MC.

So, when MC is increasing, AC' is increasing. That is, when marginal cost increases, the rate of change of average cost must increase, so average cost is always increasing when marginal cost is increasing.

Why is it possible for average cost to be decreasing while marginal cost is increasing?

Average cost can be decreasing while marginal cost is increasing due to the effect of scale. When a firm produces more output, the average cost may decline as fixed costs are spread over a larger number of units, leading to economies of scale. However, marginal cost can increase if the firm experiences diminishing returns, where adding more inputs leads to less efficient production. Thus, while each additional unit may cost more to produce, the overall average cost can still decrease if the increase in output sufficiently offsets the rising marginal costs.


If average total cost is greater than marginal cost average total cost must be increasing is the true or false?

true


How do you find marginal average cost?

Marginal cost comes from the costs of producing just one more of something.


What are benefits of marginal costing?

Marginal cost is the extra cost incurred in producing one unit of a product.If the marginal cost is more than average cost that means that costs are increasing and if it is less it means costs are decreasing.This way we find out how are business is progressing.


Is falling when marginal cost is below it and rising?

When marginal cost is below average total cost, average total cost tends to fall, as each additional unit produced is less expensive than the average of previous units. Conversely, when marginal cost is above average total cost, average total cost rises, since producing additional units adds more cost than the average. Thus, if marginal cost is falling while it is below average total cost, it could lead to a further decrease in average total cost, while rising marginal cost above average total cost would increase it.


What Relation between marginal cost and average cost?

If average cost increases does marginal cost increase?

It depends if the increase in Average Cost is caused by an increase in Fixed Costs or an increase in Variable Costs. An increase in Fixed Costs will not increase MC, because FCs do not vary with output (by definition) And increase in Variable Costs will increase MC


When is average cost minimized?

Average cost is minimized when marginal cost equals average cost. This occurs at the output level where the cost of producing one additional unit (marginal cost) is equal to the average cost of all units produced. At this point, producing additional units would either increase or decrease the average cost, indicating that the minimum average cost has been reached.


When a firm's marginal revenues are higher than its marginal cost?

Marginal cost is


Does marginal cost curve always intersect the average cost curve at the average cost curve's lowest point?

When the marginal cost is below the average total costs or the average variable costs,then the AC would be declining.When marginal cost is above the average cost then the average cost would be increasing.Therefore the marginal cost should intersect with the average cost at the lowest point in order to pull the average cost upwards.


What happens to average variable cost if the marginal cost is less than it?

If the marginal cost is less than the average variable cost, the average variable cost will decrease.


When marginal cost is less than the average total cost the average total cost is falling why?

as a marginal cost is the cost of the next product produced, if this is less than average cost, when you continue to produce more products the lower marginal cost will have an affect on the average and cause it to fall.
