Suppose that at the beginning of March, a new strain of flu, flu-A, emerges and begins to spread through U-College undergraduates. The symptoms of Flu-A are like the common flu, flu-B, and other respiratory illnesses. It is thought that the infection rate of Flu-A will be similar to that of Flu-A at other colleges, but that the disease will be much less deadly. Flu-A is expected to infect about 20 out of every 1,000 undergraduate students per month for the rest of the semester, while the flu-B is expected to infect about 30 out of every 1,000 undergraduates per month for the rest of the semester. Assume that this rate remains the same for each of the remaining months in the semester (March, April, and May). There are currently 6,800 U-College undergraduates on campus. You may assume that infection with Flu-A is independent of infection with the flu-B.
1. Calculate the total expected number of Flu-A cases among U College undergraduates over the next three months.
2. If more than 150 cases of Flu-A are observed among the undergraduates during the next month, the College will go into shut-down mode and cancel class meetings. What is the probability the College goes into shut-down mode by the end of March?

Suppose a company has invented and patented a new drug to reduce
the flu symptoms. The marginal cost of producing the drug is
constant: MC = $3. Sup??pose this drug is not covered by any
insurance plan and the market demand is as follows: What is the
equilibrium quantity? ?d =60−4?
a) How much should the firm charge per unit to maximise its
profit?
b) Suppose the drug is now covered by a government insurance
plan with a co-insurance rate...

This year’s flu, which is dominated by H3N2 (an influenza A
strain), has caused severe morbidity and mortality. The virus is
usually spread through contact with aerosols and droplets, and
introduced into epithelial cells of the respiratory tract. Both you
and your wife caught flu two-three week ago, and had miserable time
with similar symptoms although you got sick first and then she came
down 1 week later. In addition to experiencing local symptoms, like
sore throat and nasal congestion,...

New lithographic equipment, acquired at a cost of $843,200 on
March 1 at the beginning of a fiscal year, has an estimated useful
life of five years and an estimated residual value of $94,860. The
manager requested information regarding the effect of alternative
methods on the amount of depreciation expense each year. On the
basis of the data presented to the manager, the
double-declining-balance method was selected.
In the first week of the fifth year, on March 4, the equipment...

Some time ago the
swine flu bug swept across the U.S. Suppose now that a new flu bug
(the “feline” flu) is threatening the health of U.S. residents.
Assume that you work for the Harvard School of Public Health, and
that you need to quickly determine how the American public is
responding to the current feline flu issue. The objective is to
find out how people’s behavior might have recently changed because
of their concerns about contracting the flu. For...

alternative methods on the amount of depreciation expense each
year.
On March 4 of Year 5, the equipment was sold for $135,000.
