<h2>
Both situations are examples of an economic problem.</h2>
Explanation:
Let us understand the term "economic problem"
Though the expectation of the people are endless, the "resources available" to satisfy the need is limited. This causes the "economic problem".
A student trying to decide how to spend his weekly allowance:
The need of student may be endless but still he is in a position to decide only based on the amount which he has to spend. He needs to prioritize the needs and then spend accordingly.
A country choosing to sacrifice some privacy to gain more security:
Under a compelled situation, the country has to sacrifice the privacy and then have to gain security. The loss due to negotiation of privacy is for sure and this leads to economic problem.
 
        
        
        
Answer: $972,900
Explanation:
The cost of land consists of the actual purchase price, and all other expenses that are necessary to make the asset ready for its intended use. In terms of land, all these expenditures can include title fees, unpaid taxes from previous years only (i.e. not current taxes), and other expenses need to physically prepare the land for use. The current taxes figure of $4,600 is not included here, as it is only owed during the current year, therefore normal accounting rules for taxes will apply. This figure will thus be treated as a liability until it is paid. The back taxes were aqcuired when the asset was aqcuired, and thus form part of the cost. 
Old buildings that were on the land, may need to be teared down so that land can be utilised. The costs used to demolish the building also forms part of the purchase price. On top of that, to fully prepare the land for use the land may need to be landscaped and leveled. All these costs contribute towards getting the land ready for use, and are thus included in the cost. Sales made on any item related to the land, during the process when the land was still being processed for its intended use, will reduce the cost of the asset, and deduct this figure. This figure will fall under sales, which is an income to the business. The full calculation of the cost is as follows:
Purchase price: $910,000
Title insurance: + $2,400
Unpaid property taxes: + $8,300
Cost of removing building: + $45,900
Sale of salvaged materials: - $4,000
Level the land: + $10,300
Cost of land: = $972,900
 
        
             
        
        
        
Answer:
(D) Calling a patient to confirm an appointment.
Explanation:
Which among the following processes of a dentist's office is the most likely a back-office process?
A back office process is a process that supports the front office processes. In the service industry such as this - dental services - a back office process won't require the presence of the client.
THE ANSWER IS (D)
Calling a patient to confirm an appointment doesn't require facing the patient or having them around.
Filing a claim with the patient's dental insurance provider requires the presence of one or both of the client and his insurance officer.
Cleaning a patient's teeth requires his or her presence at the dental clinic.
Same with option C.
 
        
             
        
        
        
Answer:
Profit Maximisation 
Explanation:
Profit is the difference between total revenue (receipts) from sale & total cost (expenditure) on production. 
Total Revenue = Price x Quantity ; Total Cost = Average Cost x Quantity 
Economists study all the producer behaviour, based on assumption that : Goal of firm is Profit Maximisation. 
Maximising Profit implies maximising the difference between Total Revenue & Total Cost [ TR - TC] . This further leads to producer equilibrium rule of Marginal Revenue = Marginal Cost [MR = MC] ; i.e additional revenue per unit sold equals additional cost per unit production. 
 
        
             
        
        
        
Answer:
0.60
Explanation:
The midpoint formula is used to calculate elasticity by using average percentage in both price and quantity.
The formula is given below:
Percentage change in quantity =<u>  (Q2 -Q1)     </u>   x  100
                                                         (Q2 + Q1) / 2
Percentage change in price = <u> (P2 -P1)     </u>   x  100
                                                    (P2 + P1) / 2
Elasticity =<u> Percentage change in price__</u>
                  Percentage change in quantity
Inserting the data:
Percentage change in quantity =<u> (30  -20)    </u>  x  100  =    <u>10</u> x 100  = 40%
                                                        (30 + 20) /2                   25
 
 Percentage change in price  = <u>($20 - $10)</u> x 100    =  <u>10</u>  x 100   =  66.6%
                                                     ($20 + $10) /2             15
Elasticity of supply = <u>40%</u>
                                   66.6%
                                   = 0.60
