To determine Sammy's gas mileage, we need to calculate the miles per gallon (mpg). Here's a detailed, step-by-step explanation of how to find the gas mileage and round it to the nearest mpg:
1. Identify the given values:
- Miles driven: 906 miles
- Gallons of gas used: 30.2 gallons
2. Calculate the miles per gallon (mpg):
- The formula to calculate mpg is:
[tex]\[
\text{mpg} = \frac{\text{miles driven}}{\text{gallons used}}
\][/tex]
- Plug in the given values:
[tex]\[
\text{mpg} = \frac{906}{30.2}
\][/tex]
3. Compute the mpg:
- Performing the division:
[tex]\[
\text{mpg} = 30.0
\][/tex]
4. Round the mpg to the nearest whole number:
- Since 30.0 is already a whole number, we just round it to:
[tex]\[
\text{mpg rounded} = 30
\][/tex]
Therefore, Sammy's gas mileage, rounded to the nearest mpg, is 30 mpg. The correct answer is not among the provided options, but the rounded gas mileage is indeed 30 mpg.
