Answer:
a. [tex]y=38x[/tex].
Step-by-step explanation:

a. First of all, we will find mileage of Ann's car by dividing total distance traveled by total fuel consumed.
Since Ann's can travels 38 miles per gallon, so distance covered by using x gallons on gas would be [tex]38x[/tex] .
Therefore, our required equation would be [tex]y=38x[/tex].
