182 Chapter 2 Linear Equations and Inequalities in One Variable 3. In 2010, the number of wireless subscriber connections was 93% of the population of the United States. Use the previous information to approximate the U.S. population. Show the equation that was used to solve the problem. 4. Research the Internet to determine the current U.S. population. Round the population to the nearest million. Use the equation in step 1 to determine when the number of wireless subscriber connections will reach the current U.S. population. 5. The number of cell sites can be given by c = 15,552.28x + 19,662.9, where x is the years after 1995. Complete the table to determine the number of cell sites for the given years. Year Years After 1995, x Number of Cell Sites, c 1995 2000 2005 2010 6. Determine the percent increase in wireless subscriber connections and cell sites for each 5-yr period. Does the growth of cell sites meet the growth of subscribers? 5-yr Period Percent Increase in Wireless Subscriber Connections Percent Increase in Cell Sites 1995-2000 2000-2005 2005-2010 Source: www.ctia.org
