Answer 1

To find the percent increase in the price of gasoline, you can use the formula:

Percent Increase = ((New Price - Old Price) / Old Price) * 100

Plugging in the values:

Percent Increase = (($3.79 - $2.79) / $2.79) * 100
Percent Increase = ($1.00 / $2.79) * 100
Percent Increase = 0.358 * 100
Percent Increase = 35.8%

Rounded to the nearest whole percent, the percent increase in the price of gasoline from 2008 to 2009 is 36%.
