Price of Amazon’s Kindle The following table shows the price of Amazon’s Kindle 2 e-book reader. It is adapted from data available on the web. Here time is measured in months since February 2009, when the Kindle was launched.
Time | Price |
0 | $349 |
5 | $299 |
10 | $249 |
15 | $199 |
a. By calculating differences, show that these data can be modeled using a linear function.
b. Find a linear formula that models these data. Be careful about the sign of the slope.
c. What price does your formula from part b project for January 2012 (35 months after the Kindle was launched)? (Note: The web data were the basis for speculation that some day the Kindle would be free.)

- Does Table 2 represent a linear function? If so, finda linear equation that models the data.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_forwardHigh School Graduates The following table shows the number, in millions, graduating from high school in the United States in the given year. Year Number graduating in millions 1985 2.83 1987 2.65 1989 2.47 1991 2.29 a. By calculating difference, show that these data can be modeled using a linear function. b. What is the slope for the linear function modeling high school graduations? Explain in practical terms the meaning of the slope. c. Find a formula for a linear function that models these data. d.
