1 answer

To determine how many more miles per gallon Gabi can go if she uses gas from Good gas instead of Go gas, we need to calculate the difference in miles per gallon between the two brands.

For Go gas:
- Miles per gallon = Total miles driven / Total gallons used
- For the first set of data: 170.5 miles / 5.5 gallons = 31 miles per gallon
- For the second set of data: 316.2 miles / 10.2 gallons = 31.02 miles per gallon
- For the third set of data: 372.0 miles / 12.0 gallons = 31 miles per gallon
- For the fourth set of data: 449.5 miles / 14.5 gallons = 31 miles per gallon

For Good gas:
- Miles per gallon = Total miles driven / Total gallons used
- For the first set of data: 127.5 miles / 3.75 gallons = 34 miles per gallon
- For the second set of data: 319.6 miles / 9.4 gallons = 34 miles per gallon
- For the third set of data: 428.4 miles / 12.6 gallons = 34 miles per gallon
- For the fourth set of data: 544.0 miles / 16.0 gallons = 34 miles per gallon

From the data, we can see that Gabi can go 3 more miles per gallon if she uses gas from Good gas instead of Go gas.
