The economic inefficiency of a monopolist can be measured by the A. area above marginal cost but beneath demand from the monopol
Reil [10]

Answer:

The correct answer is option D.

Explanation:

A monopoly firm is neither productively nor allocative efficient. The reason behind this is that it does not utilize the resources efficiently and produces below the socially optimal level of output.  

Unlike perfect competition, which produces at the point where price equals marginal cost, a monopolist produces at the point where the price is greater than marginal cost.  

This inefficiency is visible through the decrease in consumer surplus and deadweight loss. The difference between socially optimal level of output and monopoly output also represents inefficiency. The value of the goods and services that could have been made if monopolist chose to produce at a socially optimal level also shows inefficiency.

Which of the following is not an example of safeguarding inventory? a.physical devices such as two-way mirrors, cameras, and ala
Talja [164]

Answer: The Option "d.returning inventory that is defective or broken" is NOT an example of safeguarding inventory.

Explanation: If we analyze the statements:

a.physical devices such as two-way mirrors, cameras, and alarms - These are all tools intended for protection against possible inventory theft.

b.storing inventory in restricted areas - Restricting access only to inventory-enabled personnel is able to protect the inventory much more than if anyone can access it.

c.matching receiving documents, purchase orders, and vendor's invoice - Controlling each of the purchase documents and performing the physical count reduces the possibilities of inventory differences for losses or errors.

d.returning inventory that is defective or broken - Returning the defective inventory is a post-echo action that occurred due to the unprotection of the inventory, therefore it could not be referred to as an example of inventory protection.

Assume that a piece of land is currently valued at $50,000. If this piece of land is expected to appreciate at an annual rate of
Luda [366]

Answer:

The correct answer is $132,664.89.

Explanation:

According to the scenario, the given data are as follows:

Present value (PV) = $50,000

Rate of interest (r) = 5%

Time period (n) = 20 Years

So, we can calculate future value by using following formula:

Future value = PV × (1 + r)^(n)

= $50000 × ( 1 + 5% )^20

= $50000 × (1 + 0.05)^20

= $132,664.89

Hence, After 20 years land will be worth $132,664.89.

Daniel [21]

Answer:

Weighted-average inventory costing method Ending Inventory = $ 9666.67= $ 9667

Explanation:

Date           Particulars       Units   Unit Cost        Total Cost

January 31  Purchases          300             $ 60        $ 18,000

February 28   Purchases       150             $ 25          $3750

Total                                       450                               $ 21,750

Weighted-average inventory costing method=  Total Cost/ Total Units=

                                    $ 21,750/450= $48.33 purchase price per unit

Sales              250 units       at     $ 70    =      $ 17500

Ending Units =  Purchases-Sales = 450-250= 200

Weighted-average inventory costing method Ending Inventory = $ 9666.67

200 units at 448.33=  $ 9666.67= $ 9667

Company ABC reported the following: 1. Net Income: $110,000 2. Return on Sales (Net Income/Sales): 3.56% 3. Gross Profit Percent
Sergeeva-Olga [200]

Answer:

$2,266,123.60

Explanation:

As it is given

Return on sales = Net income ÷ Sales

3.56% = $110,000 ÷ Sales

So, the sales is  $3,089,887.64

Now the Gross Profit percentage is

Gross Profit percentage = Gross profit ÷ Sales

26.66% = Gross profit ÷ $3,089,887.64

So, the gross profit

= $823,764.044

Now the cost of goods sold is

= Sales - gross profit

=  $3,089,887.64 - $823,764.044

= $2,266,123.60
