Question 1

If the price of popcorn is $0.50 per box and the price of peanuts is $0.25 per bag, and you have $5 to spend and decide to purchase 8 boxes of popcorn, the maximum quantity of peanuts that you can purchase is _______ bags.

Accepted Answer

You can spend $2 on peanuts (5-4). Since each bag of peanuts costs $0.25, you can buy 8 bags of peanuts.

Question 2

Use the following to answer question(s): Marginal Benefits and Marginal Costs
 
-(Exhibit: Marginal Benefits and Marginal Costs) In the exhibit, more time spent studying economics adds points to economics scores but subtracts points from accounting scores.When the student studies economics for 4 hours, the marginal benefit is _______ ; when the student studies for 6 hours, the marginal benefit is _______.

Accepted Answer

The marginal benefit is the additional benefit received from an additional unit of an activity. At 4 hours, the increase in economics score represents the marginal benefit of studying for that additional hour, which is 20 points. At 6 hours, the increase is only 10 points, indicating the marginal benefit of studying for the sixth hour.

Question 3

The costs economists use in the concept of economic profit are:

Accepted Answer

Economic profit considers opportunity costs, which are the value of the best alternative forgone, rather than just accounting costs.

Question 4

Activities of consumers and firms:

Accepted Answer

Both consumers and firms engage in activities that have costs and benefits. Consumers weigh the benefits they receive from a product or service against the price they have to pay for it, and firms consider the cost of production and market competition when making decisions about what products to produce and at what price. Economic theory analyzes these trade-offs and helps to explain how consumers and firms behave in the marketplace.

Question 5

Use the following to answer question(s): Marginal Benefits and Marginal Costs
 
-(Exhibit: Marginal Benefits and Marginal Costs) The marginal benefit of studying economics when the student is at 4 hours is _______ points and the marginal cost is ________ points.

Accepted Answer

At 4 hours of studying economics, the marginal benefit is 20 points and marginal cost is also 20 points. Therefore, the best choice(s) would be to continue studying economics for another hour.

Question 6

Suppose that the expected exam scores from studying economics for 0, 1, 2, or 3 hours are 65, 80, 90, and 95 points, respectively, while the expected exam scores for studying 0, 1, 2, or 3 hours of accounting are 50, 65, 70, and 70 points, respectively.With 3 total hours of study time, your combined scores can be maximized by spending _______ hours studying accounting.

Accepted Answer

To maximize combined scores, allocate study hours where the marginal gain is highest. Studying economics for 3 hours yields 95 points. Studying accounting for 1 hour and economics for 2 hours yields 65 (accounting) + 90 (economics) = 155 points, which is higher than any other combination.

Question 7

The _______ is the amount by which an additional unit of an activity increases its total benefit.

Accepted Answer

Marginal benefit is the additional benefit received from the consumption or production of one more unit of a good or service. It is important to compare the marginal benefit to the marginal cost when making decisions about resource allocation.

Question 8

Use the following to answer question(s): Marginal Benefits and Marginal Costs
 
-(Exhibit: Marginal Benefits and Marginal Costs) In the exhibit, more time spent studying economics adds points to economics scores but subtracts points from accounting scores.The student in this example would maximize net benefits by studying economics for _______ hours.

Accepted Answer

At 4 hours of studying economics, the marginal benefit and marginal cost are equal. This means that any additional time spent studying economics would lead to a net decrease in overall score. Therefore, the student would maximize net benefits by studying economics for 4 hours.

Question 9

Use the following to answer question(s): Marginal Benefits and Marginal Costs
 
-(Exhibit: Marginal Benefits and Marginal Costs) In the exhibit, more time spent studying economics adds points to economics scores but subtracts points from accounting scores.At 4 hours of study the student will "maximize" because:

Accepted Answer

At 4 hours of study, the student will maximize because this is the point where marginal benefits (MB) equal marginal costs (MC), which is also where the difference between total benefits and total costs is maximized. This encompasses all the conditions listed, making all of the options correct.

Question 10

Use the following to answer question(s): Marginal Benefits and Marginal Costs
 
-(Exhibit: Marginal Benefits and Marginal Costs) In the exhibit, more time spent studying economics adds points to economics scores but subtracts points from accounting scores.The marginal benefit of studying economics when the student is at 2 hours is _______ points and the marginal cost is _______ points.

Accepted Answer

The marginal benefit of studying economics for an additional hour when the student is at 2 hours is the increase in economics score due to that extra hour of study, which is 30 points. The marginal cost, in this context, refers to the lost points in accounting scores due to spending that additional hour on economics instead of accounting, which is 10 points.

Question 11

In economics the assumption is made that consumers and firms will make choices that maximize(s) the _______ of each activity.

Accepted Answer

The concept of rationality assumes that consumers and firms will make choices that maximize their net benefit, which is the difference between the total benefit and the total cost of each activity. Therefore, A is the correct choice.

Question 12

In order to maximize net benefit, consumers and firms evaluate each activity at the:

Accepted Answer

Evaluating activities at the margin means looking at the additional benefit or cost of doing a little more or a little less of the activity. This helps consumers and firms make decisions that maximize net benefit or profit. Therefore, C is the best choice. Option A (average) is not as useful for maximizing net benefit, as it doesn't consider the benefits and costs of small changes. Option B (top) and option D (end) are not specific enough and do not provide a clear method for evaluating activities.

Question 13

To determine the quantity of any activity that will maximize net benefit, economists employ the ________ rule.

Accepted Answer

The economists employ the marginal decision rule to determine the quantity of any activity that will maximize net benefit. This rule states that a rational decision-maker should take an action only if and only if the marginal benefit of the action exceeds the marginal cost. Therefore, the optimal quantity of an activity occurs at the point where the marginal benefit equals the marginal cost.

Question 14

Maximization of the net benefit of an activity occurs when:

Accepted Answer

Maximization of net benefit occurs when Marginal Benefit (MB) is equal to Marginal Cost (MC). This is because at this point, the added benefit gained from the activity is equal to the added cost incurred to undertake the activity. This ensures that resources are being allocated efficiently and there is no waste. If MB is greater than MC (option B), then it means that more benefit can be gained by undertaking the activity, and if MB is less than MC (option C), it means that the cost incurred is greater than the benefit gained, leading to a loss. Therefore, option A is the best choice. Option D is not accurate as MB approaching MC does not necessarily lead to maximization of net benefit.

Question 15

If the price of popcorn is $0.50 per box and the price of peanuts is $0.25 per bag, and you have $5 to spend and decide to purchase 6 boxes of popcorn, the maximum quantity of peanuts that you can purchase is _______ bags.

Accepted Answer

The cost of 6 boxes of popcorn is 6 * $0.50 = $3. This leaves $2 to spend on peanuts. Since each bag of peanuts costs $0.25, with $2 you can buy 2/$0.25 = 8 bags of peanuts.

Question 16

Net benefit is maximized when marginal benefit _______ marginal cost.

Accepted Answer

When marginal benefit (MB) equals marginal cost (MC), it means that the benefit received from the last unit consumed is equal to the cost of producing it. This is the point at which net benefit is maximized because any additional unit would result in MC being greater than MB, meaning that the cost of producing that unit would exceed the benefit received from it. Therefore, choice C is the best answer.

Question 17

Suppose that the expected exam scores from studying economics for 0, 1, 2, or 3 hours are 65, 80, 90, and 95 points, respectively, while the expected exam scores for studying 0, 1, 2, or 3 hours of accounting are 50, 65, 70, and 70 points, respectively.With 3 total hours of study time, your combined scores can be maximized by spending _______ hours studying economics.

Accepted Answer

To maximize the combined scores, we need to choose the subjects that give the highest total score for 3 hours of study time. We can calculate the total score for each possible combination of study hours as follows:

0 hours of economics + 3 hours of accounting = 50 + 70 + 70 = 190
1 hour of economics + 2 hours of accounting = 80 + 70 + 70 = 220
2 hours of economics + 1 hour of accounting = 90 + 65 + 50 = 205
3 hours of economics + 0 hours of accounting = 95 + 65 + 50 = 210

Thus, the best combination is studying 2 hours of economics and 1 hour of accounting, which gives a total score of 205. Therefore, the answer is B.

Question 18

If the price of popcorn is $0.50 per box and the price of peanuts is $0.25 per bag, and you have $10 to spend and decide to purchase 20 bags of peanuts, the maximum quantity of popcorn that you can purchase is _______ boxes.

Accepted Answer

If you spend all $10 on peanuts, you could buy 40 bags of peanuts (20 x $0.50). However, if you want to get some popcorn as well, you need to subtract the cost of the peanuts from the total budget to determine how much money you have left for popcorn: $10 - (20 x $0.25) = $5. 
Since popcorn costs $0.50 per box, you can buy a maximum of 10 boxes of popcorn with the remaining $5 ($5 ÷ $0.50 = 10). Therefore, the best choice is B) 10.

Question 19

The _______ is the amount by which an additional unit of activity increases its cost.

Accepted Answer

The definition provided matches the concept of marginal cost - the additional cost incurred by producing one more unit of a product or service.

Question 20

Maximizing choices must be made within parameters imposed by:

Accepted Answer

Maximizing choices must be done within parameters imposed by a constraint, a boundary, or a limit. Therefore, all of the above options are correct.
