Gabi can go
more miles per gallon if she uses gas from Good Gas for her car.
To determine how many more miles per gallon Gabi can go if she uses gas from Good Gas, we can compare the average miles driven per gallon for each brand.
For Go Gas:
Total miles driven = 170.5 + 316.2 + 372.0 + 449.5 = 1308.2
Total gallons of gas = 5.5 + 10.2 + 12.0 + 14.5 = 42.2
Average miles per gallon for Go Gas = Total miles driven / Total gallons of gas = 1308.2 / 42.2 = 31.02 miles per gallon
For Good Gas:
Total miles driven = 127.5 + 319.6 + 428.4 + 544.0 = 1419.5
Total gallons of gas = 3.75 + 9.4 + 12.6 + 16.0 = 41.75
Average miles per gallon for Good Gas = Total miles driven / Total gallons of gas = 1419.5 / 41.75 = 34.01 miles per gallon
So, Gabi can go approximately 34.01 - 31.02 = 2.99 more miles per gallon if she uses gas from Good Gas for her car.
