Chapter 7.6, Problem 28PPS

To determine

To calculate: The percent of change in the number of athletes participating from 2000 to 2004.

Answer to Problem 28PPS

  $4.2\%$ , Increase.

Explanation of Solution

Given information:

There were 10,651 athletes who participated in the 2000 Summer Olympics in Sydney, Australia. In the 2004 Summer Olympics in Athens, Greece, 11,099 athletes participated.

Calculation:

Number of athletes change from 2000 to 2004 $=11099-10651=448$

Then, percent of change

  $\begin{array}{l}=\frac{\text{amount of change}}{\text{original amount}}\\ =\frac{448}{10651}\\ \approx 0.04206\end{array}$

To the nearest tenth, the percent of change is $4.2\%$ . Since the percent of change is positive, it is a percent of increase.
