USA Today reported (Anthony Breznican and Gary Strauss, “Where Have All the Moviegoers Gone?” June 23, 2005) that in the summer of 2005 ticket sales to movie theaters had fallen for 17 straight weeks, the industry’s longest losing streak since 1985.

To determine the long-term trends in ticket sales, the following data representing the number of admissions

(in billions) were obtained from the National Association of Theatre Owners:

Year 1987 1988 1989 1990 1991 1992 Admissions 1.09 1.08 1.26 1.19 1.14 1.17 Year 1993 1994 1995 1996 1997 1998 Admissions 1.24 1.28 1.26 1.34 1.39 1.48 Year 1999 2000 2001 2002 2003 2004 Admissions 1.47 1.42 1.49 1.63 1.57 1.53 Year 2005 2006 2007 Admissions 1.38 1.41 1.40
