Question

] A firm is producing 1,000 units at a total cost of $5,000. If it were to increase production to 1,001 units, its total cost would rise to $5,008. What does this information tell you about the firm?

Answer 1

Answer:

The question is not complete, below is an example of the completely stated question:

A firm is producing 1,000 units at a total cost of $5,000. If it were to increase production to 1,001 units, its total cost would rise to $5,008. What does this information tell you about the firm?

a. Marginal cost is $5, and average variable cost is $8.

b. Marginal cost is $8, and average variable cost is $5.

c. Marginal cost is $5, and average total cost is $8.

d. Marginal cost is $8, and average total cost is $5.

Answer:

d. Marginal cost is $8, and average total cost is $5.  

Explanation:

Marginal cost of production is the change in cost, arising from the production of an additional unit of output. it is the cost of manufacturing one more unit of product. Mathematically, marginal cost is represented as:

$Marginal\ cost = \frac{change\ in\ cost}{change\ in\ quantity\ produced}$

change in cost (ΔC) = C₂ - C₁ = 5,008 - 5,000 = 8

change in quantity produced = Q₂ - Q₁ = 1,001 - 1,000 = 1

$Marginal\ cost = \frac{8}{1} = \ 8$

∴Marginal Cost = $8

Average Total Cost (ATC) or average cost or unit cost is the total cost divided by the number of units produced. It is represented as

$ATC =\frac{TC}{Q} \\where\\ATC = Average\ total\ cost\\\TC = Total\ cost\ = \ 5,000\\Q = units\ of\ goods\ produced = 1,000$

∴ ATC = 5,000 ÷ 1,000 = $5
