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 driven per gallon for each brand.
For Go Gas:
- Miles driven for 5.5 gallons: 170.5 miles
- Miles driven for 10.2 gallons: 316.2 miles
- Miles driven for 12.0 gallons: 372.0 miles
- Miles driven for 14.5 gallons: 449.5 miles
For Good Gas:
- Miles driven for 3.75 gallons: 127.5 miles
- Miles driven for 9.4 gallons: 319.6 miles
- Miles driven for 12.6 gallons: 428.4 miles
- Miles driven for 16.0 gallons: 544.0 miles
Now we can calculate the difference in miles driven per gallon between the two brands:
- Go Gas: (316.2 - 170.5) / (10.2 - 5.5) = 145.7 / 4.7 ≈ 31 miles per gallon
- Good Gas: (319.6 - 127.5) / (9.4 - 3.75) = 192.1 / 5.65 ≈ 34 miles per gallon
Therefore, Gabi can go 34 - 31 = 3 more miles per gallon if she uses gas from Good Gas for her car.
Go gas
Gallons of gas: 5.5, 10.2, 12.0, 14.5
Miles driven: 170.5, 316.2, 372.0, 449.5
Good gas
Gallons of gas: 3.75, 9.4, 12.6, 16.0
Miles driven: 127.5, 319.6, 428.4, 544.0
Based on the tables showing the number of miles driven per gallon of gas for two leading gas brands, Gabi determines that she should buy good gas instead of go gas. How many more miles per gallon can she go if she used gas from good gas for her car?
