Answer: A. equal to marginal cost where it intersects the demand curve
Explanation:
In a pure competition, the market is efficient because it balances demand and supply and gives an equilibrium price that takes both of them into account. 
In this market, the price is equal to the marginal revenue of a firm and the profit maximizing level of production is where the marginal revenue intersects the marginal cost. 
The efficient level is therefore where price equals marginal cost. The same goes for a natural monopoly. If economic efficiency is to be achieved, the natural monopoly's price must equal the marginal cost at the equilibrium price. 
 
        
             
        
        
        
Answer:
The correct answer is True
Explanation:
In calculating the equivalent units with respect to labor,the physical units at the start of the period is multiplied by the percentage of completion.
In other words, the equivalent units is shown thus:
Equivalent units =100000 units*20%
Equivalent units =20000 units
This implies that labor has carried  out 20% of the work required to transform the 100000 units into finished products,since only 20% work is completed, the remaining 80% is expected in the next period.

The completion of the following Medicare mathematical calculations by putting in the correct amounts is as follows:
a. Medicare payment:  $173.60
b. Patient owes Dr. Input: $226.40
c. Dr. Input’s courtesy adjustment: $50
<h3>What is the courtesy adjustment?</h3>
Courtesy adjustment is the write-off of a part of the medical bills to reduce the payment burden on the patients not fully covered by Medicare.
<h3>Data and Calculations:</h3>
Original bill = $450
Unmet deductible = $183
a. Medicare payment:  $173.60 ($400 x 43.4%)
b. Patient owes Dr. Input: $226.40 ($400 x 56.6%)
c. Dr. Input’s courtesy adjustment: $50 ($450 - $400)
