In your own words, describe what Munger means by mental models:

In my opinion Mental Models Munger (1997) is a framework for building latticework of mental models is subsidiary to cross-training for the people’s groups’ psyches. Is all the knowledge an individual can take from learning from school, home and experience and learning them very well and effective. Having this knowledge can be applied in the future on solving difficult decisions.

Describe at least one example from your own experience where your perspective or experience provided a mode of thought that brought new light to a discussion or a tough decision.

On my previous job I have an experience that I was in charge of making the owner’s manuals of the products that the company manufacture. It was really hard task because I never have done any owner’s manual before. At the end of the time frame I finished the owner manual because with all the knowledge that I obtained from school and also with the meetings from my bosses I finished a perfect manual. I found help with my bosses so they explained me how they wanted to be the manual. What information was important to publish there and which was not.

Explain how this experience has affected your decision-making process.

This experience has affected in my decision-making process because it let me think ahead to take the best decision to resolve a problem. Thinking ahead or taking action I can avoid mistakes and time consuming. Also, speaking and asking questions of unclear information is order to be clear before taking the action of making the manual without any knowledge on how to make it.

2. How many human genome equivalents are in 20 ng of cfDNA?

3. Investors have poured over 1 billion dollars into a company called “Grail” that promises ultra-sensitive early detection of cancer from one drop of blood. We routinely extract 20 ng/of cfDNA from 4 mLs of plasma. Assume one drop of blood has 40 ul of plasma. How many human genomes worth of cfDNA are in this one drop? Are claims they can detect one cancer genome among 10,000 normal cfDNA genomes well-founded?

4. Our qPCR standard is at 0.1 ng/uL. For the first qPCR standard dilution, we take 10uL of the qPCR standard and add it to 90uL TT buffer. How is this equivalent to 5000 GEs? (Note: the qPCR standard is a dilution of our LPA)

Background: Frutronics Inc. is a $2 billion dollar firm with sales in consumer products and government systems and services. Founded in 1937, Futronics Inc. has been providing reliable communications services for well over half a century. Due to a sharp increase in competition, flattened sales and external economic conditions, Futuronics is implementing a corporate overhead reduction program. The proposal is to replace the company’s central office stores by outside vendors and presents recommendations. Requirements: In a two-three page paper, discuss the option to implement outsourcing the central office functions, so as to reduce overhead and still maintain or even improve quality. The outsourcing vendors must supply the appropriate mechanism to make ordering easy, efficiently, quickly and at a cost savings. The vendors chosen must supply the current 500 products in the warehouse. If outsourcing is not the chosen action suggest strategies can be taken to reduce costs in-house?

Consider John Smith, a new freshman who has just received a study loan and started college. He plans to obtain the maximum loan at the beginning of each year. Although John Smith does not have to make any payments while he is still in school, the 6.5 percent interest per year compounded monthly owed accrued and is added to the balance of the loan.

After graduation, John Smith gets a six-month grace period. This means that monthly payments are still not required, but interest is still accruing. After the grace period, the standard repayment plan is to amortize the debt using monthly payments for 10 years.

Required:

Using the standard repayment plan and a 6.8 percent APR interest rate, compute the monthly payments John Smith owes after the grace period.
