The Consumer Price Index (CPI) is a measure of inflation obtained by comparing current prices with base prices in 1982-84. Use this information to complete the missing item in the following table for ice cream.
\begin{tabular}{|c|c|c|c|}
\hline Item & $\begin{array}{c}\text { CPI for Item in } \\
2000\end{array}$ & $\begin{array}{c}\text { CPI for Item in } \\
2009\end{array}$ & $\begin{array}{c}\text { Percent of } \\
\text { Increase }\end{array}$ \\
\hline Ice cream & 160.1 & 202.8 & \\
\hline
\end{tabular}
The percent of increase is \%. (Round to one decimal place as needed.)

Step 1 ：Given the Consumer Price Index (CPI) for ice cream in 2000 is 160.1 and in 2009 is 202.8.

Step 2 ：The percent of increase can be calculated by subtracting the initial value from the final value, dividing the result by the initial value, and then multiplying by 100 to get a percentage.

Step 3 ：Let's denote the initial value as \(I\) and the final value as \(F\). In this case, \(I = 160.1\) and \(F = 202.8\).

Step 4 ：The formula for percent increase is \(\frac{F - I}{I} \times 100\%\).

Step 5 ：Substitute \(I\) and \(F\) into the formula, we get \(\frac{202.8 - 160.1}{160.1} \times 100\%\).

Step 6 ：The percent of increase is approximately 26.670830730793266.

Step 7 ：Round to one decimal place as needed, the percent of increase is 26.7.

Step 8 ：Final Answer: The percent of increase is \(\boxed{26.7\%}\).
