Problem 5.6.8

(Requires results from Exercise 7.) According to a letter published in the Ann Landers column in the Boston Globe on Friday, December 10, 1999, When Elvis Presley died in 1977, there were 48 professional Elvis impersonators. In 1996, there were 7,328. If this rate of growth continues, by the year 2012, one person in every four will be an Elvis impersonator. a. What was the growth factor in the number of Elvis impersonators for the 19 years between 1977 and 1996? b. What would be the annual growth factor in the number of Elvis impersonators between 1977 and 1996? c. Construct an exponential function that describes the growth in the number of Elvis impersonators since 1977. d. Use your function to estimate the number of Elvis impersonators in 2012. e. Use your model for the U.S. population from Exercise 7 to determine if in 2012 one person out of every four will be an Elvis impersonator. Explain your reasoning.
