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.
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.
opportunity cost refers to the satisfaction of ones want at the expense of another want while marginal cost is the addition to total cost as a result of increasing output by one unit.
If MR is greater than MC, the firm should increase their production. The ideal amount of production is determined by allowing the marginal cost to equal the marginal revenue.
At this intersection point on a graph, firms will earn maximum profit, even if this point is under average total cost.
Marginal cost is change in total cost due to increase or decrease one unit or output. It is technique to show the effect on net profit if we classified total cost in variable cost and fixed cost.
true
Marginal cost comes from the costs of producing just one more of something.
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.
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
relation ship between average cost and marginal cost
Marginal cost is
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.
Marginal Cost will keep increasing (have upward slope) because of the principle of diminishing marginal returns. The MC curve above the its intersection with AVC is the Supply Curve *because below minimum AVC, the firms stops production)
increase output
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.
When average total cost curve is falling it is necessarily above the marginal cost curve. If the average total cost curve is rising, it is necessarily below the marginal cost curve.
Marginal cost - the derivative of the cost function with respect to quantity. Average cost - the cost function divided by quantity (q).
