answer
average variable cost is $3
question
Suppose that a business incurred implicit costs of $200,000 and explicit costs of $1 million in a specific year. If the firm sold 4,000 units of its output at $300 per unit, its accounting profits were
answer

question
Refer to the below diagram. At output level Q total fixed cost is:
answer
BCDE
question
The above diagram shows the short-run average total cost curves for five different plant sizes of a firm. The shape of each individual curve reflects
answer
increasing marginal product, followed by diminishing marginal product
question
Suppose that a business incurred implicit costs of $500,000 and explicit costs of $5 million in a specific year. If the firm sold 100,000 units of its output at $50 per unit, its accounting
answer
profits were zero and its economic losses were $500,000
question
Fixed cost is
answer
any cost which does not change when the firm changes its output
question
A firm has a fixed cost of $500 in its first year of operation. When the firm produces 100 units of output, its total costs are $4,500. The marginal cost of producing the 101st unit of output is $300. What is the total cost of producing 101 units?

answer
OBEQ
question
A firm has a fixed cost of $500 in its first year of operation. When the firm produces 100 units of output, its total costs are $3,500. When it produces 101 units of output, its total costs are $3,750. What is the marginal cost of producing the 101st unit of output?
answer
$250
question
Refer to Table 13-7. What is total output when 1 worker is hired?
answer
40
question

answer
$37
question
As Bubba's Bubble Gum Company adds workers while using the same amount of machinery, some workers may be underutilized because they have little work to do while waiting in line to use the machinery. When this occurs, Bubba's Bubble Gum Company encounters
answer
diminishing marginal product
question
Definition of Economic profit
answer
Economic profit = accounting profit - implicit costs
question
Accounting profits are typically
answer
greater than economic profits because the former do not take implicit costs into account
question
The basic characteristic of the short run is that
answer
the firm does not have sufficient time to change the size of its plant
question
As the firm in the above diagram expands from plant size #1 to plant size #3, it experiences
answer
economies of scale
question
If average total cost is declining, then
answer
marginal cost must be less than average total cost

answer
$8
question
Refer to the above diagram. At output level Q total cost is
answer
0BEQ plus BCDE
question
Assume a certain firm regards the number of workers it employs as variable but regards the size of its factory as fixed. This assumption is often realistic
answer
in the short run but not in the long run
question
