An advertising company introduces a new product to a metropolitan area of population $M$. Let $P=P(t)$ denote the number of people who become aware of the product by time $t$. Suppose that $P$ increases at a rate which is proportional to the number of people still unaware of the product. The company determines that no one was aware of the product at the beginning of the campaign $[P(0)=0]$ and that $30 \%$ of the people were aware of the product after 10 days of advertising. a. Give the differential equation that describes the number of people who become aware of the product by time $t$. b. Determine the solution of the differential equation from part (a) that satisfies the initial condition $P(0)=0$. c. How long does it take for $90 \%$ of the population to become aware of the product?

At the height of the energy shortage during the 1970s, governments were actively seeking ways to persuade consumers to reduce their energy consumption. Among other efforts undertaken, several advertising campaigns were launched. To provide input on how to design effective advertising messages, a poll was taken in which people were asked how concerned they were about shortages of gasoline and electricity. There were four possible responses to the questions:

Not concerned at all (1)

Not too concerned (2)

Somewhat concerned (3)

Very concerned (4)

A poll of 150 individuals was undertaken. Do these data provide enough evidence to allow us to infer that concern about a gasoline shortage exceeded concern about an electricity shortage?

Brian Cleary and Rita Burke filed a suit against cigarette maker Philip Morris USA, Inc., seeking class-action status for a claim of deceptive advertising. Cleary and Burke claimed that “light” cigarettes, such as Marlboro Lights, were advertised as safer than regular cigarettes, even though the health effects are the same. They contended that the tobacco companies concealed the true nature of light cigarettes. Philip Morris correctly claimed that it was authorized by the government to advertise cigarettes, including light cigarettes. Assuming that is true, should the plaintifis still be able to bring a deceptive advertising claim against the tobacco company? Why or why not? [Cleary v. Philip Morris USA, Inc., 683 F.Supp.2d 730 (N.D.Ill. 2010)]

This exercise continues the Lawlor Lawn Service, Inc., situation. Lawlor Lawn Service currently charges $100 for a standard lawn service and incurs$60 in variable cost. Assume fixed costs are $1,400 per month. Requirements

1. What is the number of lawns that must be serviced to reach break even?
2. If Lawlor desires to make a profit of$1,800, how many lawns must be serviced?

Diminishing Returns The profit $P$ (in thousands of dollars) for a company spending an amount $s$ (in thousands of dollars) on advertising is

$$P=-\frac{1}{10}s^{3}+6s^{2}+400.$$

(b) The point of diminishing returns is the point at which the rate of growth of the profit function begins to decline. Find the point of diminishing returns.

In August and September 2005, Hurricanes Katrina and Rita caused extraordinary flooding in New Orleans, Louisiana. Many homes were severely damaged or destroyed; of those that survived, many required extensive cleaning. It was thought that cleaning flood-damaged homes might present a health hazard due to the large amounts of mold present in many of the homes. The article “Health Effects of Exposure to Water-Damaged New Orleans Homes Six Months After Hurricanes Katrina and Rita” reports that in a sample of 365 residents of Orleans Parish who had participated in the cleaning of one or more homes, 77 had experienced symptoms of wheezing, and in a sample of 179 residents who had not participated in cleaning, 23 reported wheezing symptoms (numbers read from a graph). Can you conclude that the frequency of wheezing symptoms is greater among those residents who participated in the cleaning of flood-damaged homes?
