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>
Answer:
e. content; communications
Explanation:
The website content refers to all multimedia and text found on it. Content should always be relevant and aligned with the company's overall communications plan.
A key part of<u> </u><u><em>integrated marketing communications (IMC)</em></u> is the fact that a company should have all of its media deliver a consistent marketing message. That applies to the website's content and communications too, as it must integrate those factors with other media and platforms. All the media should cover the same topics - company promotions, product innovation or special customer incentives.
<em>Context, commerce </em>and<em> connection</em> are irrelevant terms for the IMC concept.
Answer: All of the above
Explanation:
The options include:
a. It's available 24 hours a day, 7 days a week.
b. All reports are handled in a highly confidential manner.
c. You do not have to identify yourself on the call.
d. All of the above.
An ethics line refers to the anonymous on-line system which can be used by an employee to report bad behavior or something unethical or illegal.
Ethics line are typically available 24 hours a day, 7 days a week and reports made are confidential. Therefore, the correct option is "All of the above".
Answer:
Consumer surplus is $15.99.
Explanation:
Melanie decided to buy a coat priced $79.95.
When she brought a coat to the sales clerk, she found out that it is on a 20% discount and she has to $15.99 less than the original price.
This means that her consumer surplus is at least $15.99.
The consumer surplus is the difference between the maximum price a consumer is willing to pay and the price it actually pays.
Melanie was willing to pay $79.95. But she actually paid $63.96. The difference between the two is $15.99.
The answer is: 1990 - 2000
By this time period, more people realize that energy generated from hydroelectric power is much more sustainable compared to other alternatives since it mostly relied on renewable resources. Between this period of time, nations on average use 2000 - 2500 billion kwh from hydroelectric power.
