Answer 1

To list the prices of gasoline from least expensive to most expensive, we need to compare the prices as numbers. Here are the prices given:

• 2.725 (April 2010)
• 2.87 (May 2010)
• 2.674 (June 2010)
• 2.67 (July 2010)

Now, arranging them in ascending order:

1. 2.67
2. 2.674
3. 2.725
4. 2.74
5. 2.87

Thus, the correct list showing the prices from least expensive to most expensive is:
