Gabi can go
more miles per gallon if she uses gas from Good Gas for her car.
To find out how many more miles per gallon Gabi can go if she uses gas from Good Gas for her car, we need to compare the average miles driven per gallon of gas for both brands.
For Go Gas:
Total gallons of gas = 5.5 + 10.2 + 12.0 + 14.5 = 42.2 gallons
Total miles driven = 170.5 + 316.2 + 372.0 + 449.5 = 1308.2 miles
Average miles per gallon = Total miles driven / Total gallons of gas = 1308.2 / 42.2 = 31.0 miles per gallon
For Good Gas:
Total gallons of gas = 3.75 + 9.4 + 12.6 + 16.0 = 41.75 gallons
Total miles driven = 127.5 + 319.6 + 428.4 + 544.0 = 1419.5 miles
Average miles per gallon = Total miles driven / Total gallons of gas = 1419.5 / 41.75 = 34.0 miles per gallon
Therefore, Gabi can go 34.0 - 31.0 = 3 more miles per gallon if she uses gas from Good Gas for her car.
