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 miles driven per gallon for both brands.
From the Go Gas table, we can see that the miles driven are 170.5, 316.2, 372.0, and 449.5 for respective gallons of 5.5, 10.2, 12.0, and 14.5.
From the Good Gas table, we can see that the miles driven are 127.5, 319.6, 428.4, and 544.0 for respective gallons of 3.75, 9.4, 12.6, and 16.0.
To find the difference in miles per gallon, we subtract the miles driven of Go Gas from the miles driven of Good Gas for each respective gallon:
For 5.5 gallons:
Good Gas - Go Gas = 127.5 - 170.5 = -43
For 10.2 gallons:
Good Gas - Go Gas = 319.6 - 316.2 = 3.4
For 12.0 gallons:
Good Gas - Go Gas = 428.4 - 372.0 = 56.4
For 14.5 gallons:
Good Gas - Go Gas = 544.0 - 449.5 = 94.5
So, Gabi can go 43, 3.4, 56.4, and 94.5 more miles per gallon if she uses gas from Good Gas for her car.
