Q: Suppose a business uses marginal analysis to decide whether to produce one more unit of a product. Which equation best represents the decision rule?

$$\text{Produce if } \text{Marginal Benefit} \u003e \text{Marginal Cost}$$

Q: Which equation best represents the opportunity cost of producing more of good A in terms of good B?

$$\text{Opportunity Cost of A} = \frac{\text{Decrease in B}}{\text{Increase in A}}$$

Question 1

Accepted Answer

The value of the next best alternative forgone when making a choice.

Question 2

Question 7

Which scenario best illustrates a trade-off?

Accepted Answer

A company must reduce production of one product to increase production of another due to limited machinery.

Question 8

If a point lies inside the Production Possibilities Frontier (PPF), what does this indicate?

Accepted Answer

Resources are underutilized or inefficiently used.

Question 9

A government faces a 'guns versus butter' dilemma. If it allocates more resources to defense ('guns'), what is the opportunity cost?

Accepted Answer

The value of healthcare and education ('butter') forgone.

Question 10

Which of the following is NOT a reason why trade-offs occur?

Accepted Answer

Resources are unlimited.

Question 11

If a business is operating at a point on the PPF, what does this imply about its resource use?

Accepted Answer

The business is maximizing production with available resources.

Question 12

Which equation best represents the opportunity cost of producing more of good A in terms of good B?

Accepted Answer

$$	ext{Opportunity Cost of A} = \frac{	ext{Decrease in B}}{	ext{Increase in A}}$$

Question 13

Which of the following best illustrates the concept of scarcity?

Accepted Answer

A factory has limited labor and machinery to produce goods.

Question 15

Question 19

Which equation represents the relationship between scarcity and trade-offs?

Accepted Answer

$$	ext{Scarcity} ightarrow 	ext{Choices} ightarrow 	ext{Trade-offs}$$

Question 20
