![\text{Mileage}=\frac{\text{20,105.5 miles}-\text{19,874.5 miles}}{\text{16.5 gallons}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/8rd1af3l200b849cja2q7w6jxvcewn170j.png)
![\text{Mileage}=\frac{\text{231 miles}}{\text{16.5 gallons}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/3zatyyuk5oq9oi0ay5ymbdxvi0gz32dc5n.png)
![\text{Mileage}=14\frac{\text{miles}}{\text{gallon}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/6sbirs81ewdwe8ibfipmcazpgksq2rzfng.png)
Therefore, the driver get a mileage of 14 miles per gallons.
