Answer:
a. y = 38x
b. 266 miles.
Step-by-step explanation:
Let y represent distance in miles and x represent gallons of gas.
a. First of all, we will find the mileage of Ann's car by dividing the total distance traveled by the total fuel consumed.
Since Ann's can travel 38 miles per gallon, so distance covered by using x gallons on gas would be.
Therefore, our required equation would be.
b. To find the distance covered by Ann's car using 7 gallons, we will substitute in the equation: Therefore, Ann's car will travel 266 miles in 7 gallons of gas.
