Both transportation and assignment problems are members of a category of lp problems called network flow problems
<h3>What is
network flow problems?</h3>
Network flow problems are a type of combinatorial optimization problem in which the input is a flow network (a graph with numerical capacities on its edges) and the goal is to construct a flow with numerical values on each edge that respect the capacity constraints and have incoming flow.
A company, for example, may want to ship packages from Los Angeles to New York City by using trucks to transport between intermediate cities. If the route connecting two cities only has one truck and each truck has a maximum load, the graph describing the transportation options will be a flow network.

Answer:
The marginal benefit from selling the vane without restoring it is $200.
Explanation:
Marginal benefits are the extra income a company can get from selling one additional unit of production.
Zane had already spent $250 in purchasing the vane and the restoration process.
Zane has two options:
- Sell the vane as it is for $200.
- Keep restoring the vane, spend $200 more and sell the vane for $500.
If Zane decides to sell the vane as it is, his marginal benefit will be $200. That would not be enough to cover his costs, this transaction will result in a $50 loss.
If Zane decides to continue the restoration, then his marginal costs will be $200 extra, but his marginal benefit would be $500. If he chose this option he could end up earning a $50 profit.
Answer:
e. $638
Explanation:
payment to be made as per forward contract (IN $)
= 39960/ 1.682
= $23757.43
now the actual rate after 90 days is 1.638
payment at 1.638 rate = 39960/ 1.638
= $24395.6
loss by hedging = $24395.6 - $23757.43
= $638.17
Therefore, The U.S. firm have saved or lost $638 in U.S. dollars by hedging its exchange rate exposure.
The project's projected NPV is $185.11. (second option)
<h3>What is the NPV?</h3>
Net present value is the present value of after-tax cash flows from an investment less the amount invested. Only projects with a positive NPV should be accepted.
A project with a negative NPV should not be chosen because it isn't profitable. NPV is calculated by taking the present value of all cash flows over the life of a project. Then, the present value of cash flows is subtracted from the investment's initial investment
NPV = -1200 + 400 / 1.0975 + 425 / 1.0975² + 450 / 1.0975³ + 475 / 1.0975^4
= $185.11

Answer: See explanation
Explanation:
According to James Grunig, professor emeritus of public relations at the University of Maryland, the five possible objectives for a communicator are:
• Message Exposure - This refers to situation when the intended people get exposed to the message that is being shared. Here, materials are provided to the mass media by the PR personel.
• Accurate dissemination of message - Messages must be passed across and communicated as clearly as possible without giving out false information or witholding back some information which is vital for the accuracy of the information delivered.
• Acceptance of the message - The message passed must be accepted by the person that's being addressed.
• Attitude change - There must be an attitude change after the message has been delivered as these shows acceptance and products should be purchased.
• Change in overt behavior - Overt behavior is openly seen and hence, there will be change in overt behavior and the goods will be purchased.
