#3
What is the formula for calculating total cost in economics?
Total cost = Fixed cost / Quantity
Total cost = Variable cost / Quantity
Total cost = Fixed cost + Variable cost
Total cost = Marginal cost * Quantity

Capital
Price
Revenue
#6
Which of the following is NOT a short-run cost?
Fixed cost
Variable cost
Marginal cost
Total cost
#7
In economics, what does the law of diminishing marginal returns state?
As production increases, total cost decreases
As more units of a variable input are added to fixed inputs, eventually the additional output decreases
As production increases, marginal cost decreases
As more units of a variable input are added, total output remains constant
#8
What is the relationship between average product and marginal product when average product is at its maximum?
Marginal product is zero
Marginal product equals average product
Marginal product is increasing
Marginal product is decreasing
#9
In the short run, a firm's average variable cost curve is typically _____?
U-shaped
Horizontal
Vertical
Downward sloping
#10
What does the concept of economies of scale refer to?
When average total cost increases as output increases
When average total cost remains constant as output increases
When average total cost decreases as output increases
When marginal cost equals average total cost
#11
What is the relationship between marginal cost and marginal product in the short run?
Marginal cost increases as marginal product increases
Marginal cost decreases as marginal product increases
Marginal cost remains constant as marginal product increases
Marginal cost and marginal product are unrelated in the short run
#12
Which of the following statements is true regarding the long run in economics?
All costs are fixed
There are no fixed costs
There are no variable costs
There are no production decisions to be made
#13
What does the production function represent?
The relationship between total cost and total output
The relationship between input and output quantities
The relationship between marginal cost and marginal product

A curve representing the relationship between marginal cost and marginal product
#15
What is the slope of the total product curve when marginal product is at its maximum?
Zero
Positive
Negative
Undefined
#16
What does the term 'marginal rate of technical substitution' refer to?
The rate at which one input can be substituted for another while keeping output constant
The rate at which total cost changes as output changes
The rate at which total product changes as input changes
The rate at which total revenue changes as price changes
#17
What is the primary assumption of the law of diminishing marginal returns?
All inputs are fixed
All inputs are variable
At least one input is fixed
At least one input is variable
