After all your hard work and receiving your BNCM degree

WEEK5
Congratulations! After all your hard work and receiving your BNCM degree, you were able to land your dream network engineering job in your company’s network operations center (NOC).
It’s your third week on the job and your manager comes to you to help out with one of their ongoing challenges – having accurate data to manage all the diverse corporate networks and links. She knows that the company needs to get better with remote monitoring and has heard about RMON and RMON probes. Although she has a basic understanding, she is now wondering if these could be the answer.
She knows that you’ve had much experience in researching, analyzing and reporting on new technology during your academic career, and this is exactly what she needs now – for real. She has asked you to research and report on what RMON and RMON probes are and how they are utilized in enterprise network management systems and how they would benefit the company.
She needs your report to be thorough but not overwhelming and has decided that five to seven pages are ideal. She is scheduled to brief the Executive committee the middle of next week and has given you one week to deliver your report. It’s your time to shine!

Suppose that the U.S. Department of Agriculture (USDA) administers the price floor for cheese

Suppose that the U.S. Department of Agriculture (USDA) administers the price floor for cheese, set at $0.17 per pound of cheese. (In real life the actual price floor was officially set at $16.10 per hundredweight of cheese. One hundredweight is 100 pounds.) At that price, according to data from the USDA, the quantity of cheese produced in 2009 by U.S. producers was 212.5 billion pounds, and the quantity demanded was 211 billion pounds. To support the price of cheese at the price floor, the USDA had to buy up 1.5 billion pounds of cheese. The accompanying diagram shows supply and demand curves illustrating the market for cheese.
a. In the absence of a price floor, the maximum price that a few of the consumers are willing to pay is $0.20 for a pound of cheese whereas the market equilibrium price is $0.13 per pound. The graph also shows that the minimum price at which a few of the producers are willing to sell is $0.06 per pound. In the absence of a price floor, how much consumer surplus is created?
b. How much producer surplus?
c. What is the total surplus?
d. The maximum price that a few of the consumers are willing to pay is $0.20 per pound of cheese, and the price floor is set at $0.17 per pound. With the price floor at $0.17 per pound of cheese, consumers buy 211 billion pounds of cheese. How much consumer surplus is created now?
e. The minimum price at which a few of the producers are willing to sell a pound of cheese is $0.06, and the price floor is set at $0.17 per pound. With the price floor at $0.17 per pound of cheese, producers sell 212.5 billion pounds of cheese (some to consumers and some to the USDA). How much producer surplus is created now?
f. The surplus cheese USDA buys is the difference between the quantity of cheese producers sell (212.5 billions of pounds of cheese) and the quantity of cheese consumers are willing to buy at the price floor (211 billions of pounds of cheese). How much money does the USDA spend on buying up surplus cheese?
g. Taxes must be collected to pay for the purchases of surplus cheese by the USDA. As a result, total surplus (producer plus consumer) is reduced by the amount the USDA spent on buying surplus cheese. Using your answers for parts d, e, and f, what is the total surplus when there is a price floor?
h. How does this compare to the total surplus without a price floor from part c?
