Concept explainers
Demand and Profit To generate a profit from its new o’Tunes service, OHaganBooks.com needs to know how the demand for music albums depends on the price it charges. During the first week of the service, it was charging $7 per album and sold 500. Raising the price to $9.50 had the effect of lowering demand to 300 albums per week.
a. Use the given data to construct a linear demand equation.
b. Use the demand equation you constructed in part (a) to estimate the demand if the price were raised to $12 per album.
c. Using the information on cost given in Exercise 39, determine which of the three prices ($7, $9 .50, and $12) would result in the largest weekly profit, and the size of that profit.

- Does Table 2 represent a linear function? If so, finda linear equation that models the data.arrow_forwardLIFE SCIENCE APPLICATIONS HIV Infection The time interval between a persons initial infection with HIV and that persons eventual development of AIDS symptoms is an important issue. The method of infection with HIV affects the time interval before AIDS develops. One study of HIV patients who were infected by intravenous drug use found that 17 of the patients had AIDS after 4 years and 33 had developed the disease after 7 years. The relationship between the time interval and the percentage of patients with AIDS can be modeled accurately with a linear equation. Source: Epidemiologic Review. a. Write a linear equation y=mt+b that models these data, using the ordered pairs (4,0.17) and (7,0.33). b. Use your equation from part a to predict the number of years before half of these patients will have AIDS.arrow_forwardSales Barnes & Noble had annual sales of $6.8 billion in 2013 and $6.1 billion in 2015. Use the Midpoint Formula to estimate the sales in 2014. Assume that the annual sales followed a linear pattern.arrow_forward
