If a monopolist or a perfectly competitive firm is producing at break-even point then they're basically equaling their average revenue to the average total cost - ii.
This basically means that they are operating at a level where the amount which they produce relates to the amount they spend.
Answer:
Purchases= $1,091,000
Explanation:
Giving the following information:
Beginning Raw materials inventory = $549,000
Ending Raw materials inventory= $612,000
The raw materials used in production= $1,028,000.
<u>To calculate the raw material purchased, we need to use the following formula:</u>
Purchases= production + ending inventory - beginning inventory
Purchases= 1,028,000 + 612,000 - 549,000
Purchases= $1,091,000
Based on efficiency, the businesses that should cut hair are the A and C; moreover, to meet the demand, each firm will need to offer at least two haircuts.
The supply of a product or the units of a product that is offered to potential customers should always meet the number of real customers. In the same way, the price of the product should meet the price customers are willing to pay.
In this context, the best is that only firm A and C cut hair, this is because their prices per cut ($25 and $30) match the consumers' willingness to pay this includes Lorenzo ($35), Gilberto ($50), Juanita ($40) and Neha ($25).
- Firm A can cut Neha's and Lorenzo's hair
- Firm C can cut Gilberto's and Juanita's hair
Moreover, this implies each firm needs to do at least 2 haircuts to cover all the possible customers.
In the case of firms B and D, the price per cut is high ($40 - $45). Based on this, they should not cut hair as only a few customers can pay for this service, and this would be inefficient.

Answer:
They should operate Mine 1 for 1 hour and Mine 2 for 3 hours to meet the contractual obligations and minimize cost.
Explanation:
The formulation of the linear programming is:
Objective function:
Restrictions:
- High-grade ore: 
- Medium-grade ore: 
- Low-grade ore: 
- No negative hours: 
We start graphing the restrictions in a M1-M2 plane.
In the figure attached, we have the feasible region, where all the restrictions are validated, and the four points of intersection of 2 restrictions.
In one of this four points lies the minimum cost.
Graphically, we can graph the cost function over this feasible region, with different cost levels. When the line cost intersects one of the four points with the lowest level of cost, this is the optimum combination.
(NOTE: it is best to start with a low guessing of the cost and going up until it reaches one point in the feasible region).
The solution is for the point (M1=1, M2=3), with a cost of C=$680.
The cost function graph is attached.
Answer: The correct answer is "universal".
Explanation: In a <u>universal</u> banking system, commercial banks engage in securities underwriting, but separate subsidiaries conduct the different activities. Also, banking and insurance are not typically undertaken together in this system.
It is the most common type of banking system and is the most commonly used.
