To find the difference in miles per gallon between Good Gas and Go Gas, we can subtract the number of miles driven by Go Gas from the number of miles driven by Good Gas for each data point.
For the first data point:
Good Gas: 127.5 miles / 3.75 gallons = 34 miles per gallon
Go Gas: 170.5 miles / 5.5 gallons = 31 miles per gallon
Difference: 34 - 31 = 3 miles per gallon
For the second data point:
Good Gas: 319.6 miles / 9.4 gallons = 34 miles per gallon
Go Gas: 316.2 miles / 10.2 gallons = 31 miles per gallon
Difference: 34 - 31 = 3 miles per gallon
For the third data point:
Good Gas: 428.4 miles / 12.6 gallons = 34 miles per gallon
Go Gas: 372.0 miles / 12.0 gallons = 31 miles per gallon
Difference: 34 - 31 = 3 miles per gallon
For the fourth data point:
Good Gas: 544.0 miles / 16.0 gallons = 34 miles per gallon
Go Gas: 449.5 miles / 14.5 gallons = 31 miles per gallon
Difference: 34 - 31 = 3 miles per gallon
Therefore, Gabi can go 3 more miles per gallon if she uses gas from Good Gas for her car.
