Concept explainers
As gas prices surge, more Americans are cycling as a way to save money, stay fit, or both. In 2010, Boston installed 20 miles of bike lanes and New York City added more than 50 miles. The bar graph shows the number of bicycle- friendly U.S. communities, as designated by the League of American Bicyclists, for selected years from 2003 through 2011.
The formula
Models the number of bicycle- friendly communities, B, x years after 2003.
Use the formula to find the number of bicycle- friendly communities in 2011. Round to the nearest whole number. Does this rounded value underestimate or overestimate the number shown by the graph? By how much?
Use the formula to determine the year in which 826 U.S communities will be bicycle friendly.
