Gas prices averaged $4.33 per gallon in January and $3.89 per gallon in February. What was the percent decrease of the average gas price from January to February?

8.98% 10.16% 11.31% 44%

To find the percent decrease, we use the following formula:

\[
\text{Percent Decrease} = \frac{\text{Old Price} - \text{New Price}}{\text{Old Price}} \times 100
\]

Where:
- Old Price = $4.33 (January price)
- New Price = $3.89 (February price)

Now, let's calculate:

\[
\text{Percent Decrease} = \frac{4.33 - 3.89}{4.33} \times 100
\]
\[
\text{Percent Decrease} = \frac{0.44}{4.33} \times 100 \approx 10.16\%
\]

So, the percent decrease in the average gas price from January to February is approximately **10.16%**.
