To calculate: The percentage of change in number of people that participated in bicycle riding from 2004 to 2006.

Answer to Problem 29PPS
The percentage of change from 2004 to 2006 is
Explanation of Solution
Given:
According to the National Sporting Goods Association, the number of people who participated in bicycle riding in 2004 was
Calculation:
The number of people participated in bicycle riding in 2004
The number of people participated in bicycle riding in 2006
Therefore, the number of people changed from 2004 to 2006
Then, the percentage of people changed from 2004 to 2006
Rounding to the nearest tenth
Conclusion:
The percentage of change from 2004 to 2006 is
