GIVEN:
If the EPA rating for a car is 22 mpg.
Required;
To calculate the amount of fuel needed for a 763-mile trip.
Step-by-step solution;
At the rate of 22 miles per gallon, a one-mile trip would require;
![\begin{gathered} 22\text{ }miles=1\text{ }gallon \\ \\ 1\text{ }mile=(1)/(22)\text{ }gallons \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/py0qotjpziezdn5qjdyzelbx35vbv13bsz.png)
Hence, for a 763-mile trip, the amount of fuel needed will be;
![\begin{gathered} 763\text{ }miles=((1)/(22)*763)\text{ }gallons \\ \\ 763\text{ }miles=34.6818181818\text{ }gallons \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/bw7k6e12rh5tql9iaivrza01hplcff7509.png)
Rounded up to the nearest whole number we now have;
ANSWER:
763 miles would require about 35 gallons of fuel
