Answer:
b. environmental issues
c. global economy
Explanation:
Changes in the environment, such as pollution and global warming, affect operations and profitabiity.
The global economic crisis slows down organizational performance.
The <u>law of increasing relative cost </u>states that the opportunity cost of producing a good always rises as one produces more of it.
According to the law of increasing costs, production eventually loses efficiency as it grows. The labor expenses for each additional item will increase, for instance, if increased production requires overtime work from your workforce.
Opportunity cost is the value of other commodities or services you must forgo in order to get your desired item. The term "cost" as used by economists often refers to opportunity cost. Cost is frequently mentioned in conversations or on the news.
According to the law of increasing opportunity cost, the cost of manufacturing the next unit rises as you keep up with the production of a given good.

Answer: The actual rate of the mortgage is 5.27%.
Since we're taking two mortgages for a total of $200,000 for 30 years, we can find the actual rate of the mortgage by finding the weighted average of the two rates. The weights in this case will be the proportion of loan taken at each rate
We have
Rates Weights Rates * Weights
4.15 0.80 
9.75 0.20 
Total 5.27%
Answer
Before I answer this question, you must note that the equilibrium price is created by both the amount supplied of a certain product as well as how much "customers" there are (or the amount that is bought in all). This however, is usually not taking account any potential competitors.
For example, let say that the price in creating the product (or buying) is $15. This means that right now, the company loses $15 for one of the products. To make a profit, the selling price must be >$15. However, (unless they are a monopoly, such as, for example, electrical companies) there are competitors that they must fight with to get customers. Of course, there are other things that can affect the price, depending on the demographic and area.
So how does supply and demand affect the equilibrium price? The limits of the supply & the amount of demand would help determine the price by the amount of people buying and the supply of the product.

Answer:
this is a cost minimization problem, but it is missing some numbers, so I looked for similar questions (see attached PDF):
minimization equation = 20x₁ + 22x₂ + 18x₃ (costs per ton)
where:
x₁ = mine I
x₂ = mine II
x₃ = mine III
the constraints are:
4x₁ + 6x₂ + x₃ ≥ 54 (high grade ore)
4x₁ + 4x₂ + 6x₃ ≥ 65 (low grade ore)
x₁, x₂, x₃ ≤ 7 (only 7 days per week)
using solver, the optimal solution is
2x₁, 7x₂, and 5x₃
a. The number of days Mine I should operate = <u>2 days
</u>
b. The number of days Mine Il should operate = <u>7 days
</u>
c. The number of days Mine III should operate = <u>5 days
</u>
d. The total cost of the operation for next week = <u>$284,000</u>
