Question 1

Johnny is a sophomore in college and has a 1.5 cumulative grade point average (GPA). Johnny's cumulative GPA will fall even further next semester if he performs worse than
(i)his cumulative GPA.
(ii)he ever performed before.

Question 4

Diminishing marginal product suggests that the marginal

Accepted Answer

Diminishing marginal product occurs when adding a new unit of input (such as hiring an extra worker) leads to a decrease in the marginal product of that input. This means that the additional output added by each subsequent worker decreases as more workers are added. Therefore, the correct answer is C since the product of an extra worker is less than the previous worker's marginal product.

Question 5

Scenario 13-20
Suppose that a given firm experiences decreasing marginal product of labor with the addition of each worker regardless of the current output level.
-Refer to Scenario 13-20. Average total cost will be

Accepted Answer

With decreasing marginal product of labor, the firm will experience higher costs as additional workers are hired. This will lead to a U-shaped average total cost curve, where average costs will decrease initially but start to rise again as diminishing returns set in.

Question 7

Thirsty Thelma owns and operates a small lemonade stand. When Thelma is producing a low quantity of lemonade she has few workers and her equipment is not being fully utilized. Because she can easily put her idle resources to use,

Accepted Answer

When Thelma is producing a low quantity of lemonade, her equipment is not being fully utilized and she has idle resources. This means that the marginal cost of one more glass of lemonade is smaller than if output were high. In other words, her costs are not increasing as quickly as her output, so it is more efficient for her to produce more lemonade at a lower cost.

Question 8

Johnny is a sophomore in college and has a 1.5 cumulative grade point average (GPA). Johnny's cumulative GPA will be better next semester if he
(i)performs better than he did last semester.
(ii)performs better than his cumulative GPA.
(iii)gives an average performance.

Accepted Answer

To improve his cumulative GPA, Johnny needs to perform better than his current cumulative GPA of 1.5.

Question 11

Marginal cost increases as the quantity of output increases. This reflects the property of

Accepted Answer

Diminishing marginal product occurs when more and more units of a variable input are added to a fixed input, resulting in each additional unit of the variable input leading to a smaller increase in output. This causes the marginal cost to increase as the quantity of output increases since more units of the variable input are needed to produce each additional unit of output.

Question 12

Scenario 13-20
Suppose that a given firm experiences decreasing marginal product of labor with the addition of each worker regardless of the current output level.
-Refer to Scenario 13-20. Average variable cost will be

Accepted Answer

Since the marginal product of labor is decreasing, the cost of producing additional units of output will be increasing with each additional worker. As a result, the average variable cost, which includes the cost of labor, will also be increasing. Therefore, the correct answer is A, rising at all points.

Question 13

Jennifer is a junior in college. Her current cumulative grade point average (GPA) is 3.5 out of a 4.0 scale. Jennifer is hoping that by the time she graduates, she can raise her cumulative GPA to a 3.7. Which of the following statements is correct?

Accepted Answer

Jennifer's current cumulative GPA is 3.5, and in order to raise it to a 3.7, she must earn higher than a 3.7 in her senior year. This is because the cumulative GPA represents the average of all the grades she has earned, including the grades she has already earned in her previous semesters. Therefore, if she only earns a 3.7 in her senior year, it will not be enough to raise her cumulative GPA to a 3.7.

Question 14

Suppose that a firm has only one variable input, labor, and firm output is zero when labor is zero. When the firm hires 6 workers the firm produces 90 units of output. Fixed costs of production are $6 and the variable cost per unit of labor is $10. The marginal product of the seventh unit of labor is 4. Given this information, what is the marginal cost of production when the firm hires the 7th worker?

Accepted Answer

To find the marginal cost of production when the firm hires the 7th worker, we need to use the formula:

Marginal Cost = (Change in Total Cost) / (Change in Quantity)

We know that the variable cost per unit of labor is $10, so hiring the 7th worker will increase variable costs by $10.

To calculate the change in total costs, we need to know the total cost of producing 6 units and 7 units of output, respectively.

Total cost for 6 units of output = fixed costs + (variable cost per unit of labor * quantity of labor) 
Total cost for 6 units of output = $6 + ($10 * 6) 
Total cost for 6 units of output = $66

Total cost for 7 units of output = fixed costs + (variable cost per unit of labor * quantity of labor) 
Total cost for 7 units of output = $6 + ($10 * 7) 
Total cost for 7 units of output = $76

Therefore, the change in total cost is $10 ($76 - $66).

The change in quantity is 1 (from 6 workers to 7 workers).

So, the marginal cost of production when the firm hires the 7th worker is:

Marginal Cost = (Change in Total Cost) / (Change in Quantity)
Marginal Cost = $10 / 1
Marginal Cost = $10

Therefore, the best choice is B, $2.50.

Question 19

If marginal cost is rising,

Accepted Answer

If marginal cost is rising, it means that each additional unit of production is becoming more costly to produce. This indicates that the marginal product of the variable input (such as labor or raw materials) is falling. Therefore, choice C is the correct answer. Choices A and B are not necessarily true and may depend on the specific cost and production structure. Choice D is incorrect as a rising marginal cost indicates a falling marginal product, not a rising one.

Question 20

Diminishing marginal product suggests that

Accepted Answer

Diminishing marginal product occurs when adding an additional unit of input (such as labor) to a fixed amount of other inputs (such as capital) results in a smaller increase in output than the previous unit of input. This means that the additional units of input become less productive and therefore more costly, leading to an upward sloping marginal cost curve. Thus, the correct answer is B.
