Re: Advertising for Oracular

Oracular Consulting wants to increase its exposure to the public in order to increase business. We are planning to split our advertising budget among three venues:

We have a maximum of $50,000 to spend on advertising per month. Ads in the airline magazine cost $25,000 for a one page ad each month. The magazine is seen by about 600,000 people each month. The newspaper ads cost $210 per square inch for an ad that runs in all four Sunday issues in one month. The smallest ad available is four square inches; the largest is a half-page ad (115 square inches). The newspaper has a circulation of 900,000. Market research has shown that the number of people who pay enough attention to the ad to count as having seen it is dependent on the number of square inches of the ad according to the formula (where ”units” stands for the number of units, in square inches, of the ad):

Exposure =  - 68.05⋅Units2 + 14504.6⋅Units

The web ads are randomly generated whenever someone visits the web site. The price we pay is based on the priority our ad is assigned. For every 0.1% chance of our ad being shown, we pay $60. The website will not allow us to purchase more than 25% of the ad space. The web site gets an average of 800,000 hits per month. Obviously, we want Oracular to be seen by as many people as possible. Keep in mind, though, that many of the circulation numbers above are approximate, so give us some idea of what range of results we can expect if these numbers change. Also, you should be aware that Albatross Airlines has been having some difficulties lately, and the number of passengers is expected to drop; they will probably raise prices for ads to compensate a little. We need to know at what point we should stop advertising in their magazine. Finally, the monthly advertising budget fluctuates as much as $10,000 per month; how will that effect our decisions about what ads to place?
