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 uses gas from Good Gas for her car?

Answer 1

To determine how many more miles per gallon Gabi can drive with Good Gas compared to Go Gas, we need to calculate the miles per gallon (MPG) for both gas brands based on the provided data.

Calculation of MPG for Go Gas:

1. 5.5 gallons:
   Miles = 170.5
   MPG = 170.5 / 5.5 = 31.00

2. 10.2 gallons:
   Miles = 316.2
   MPG = 316.2 / 10.2 = 31.00

3. 12.0 gallons:
   Miles = 372.0
   MPG = 372.0 / 12.0 = 31.00

4. 14.5 gallons:
   Miles = 449.5
   MPG = 449.5 / 14.5 = 31.00

Average MPG for Go Gas:
(31.00 + 31.00 + 31.00 + 31.00) / 4 = 31.00 MPG

Calculation of MPG for Good Gas:

1. 3.75 gallons:
   Miles = 127.5
   MPG = 127.5 / 3.75 = 34.00

2. 9.4 gallons:
   Miles = 319.6
   MPG = 319.6 / 9.4 = 34.00

3. 12.6 gallons:
   Miles = 428.4
   MPG = 428.4 / 12.6 = 34.00

4. 16.0 gallons:
   Miles = 544.0
   MPG = 544.0 / 16.0 = 34.00

Average MPG for Good Gas:
(34.00 + 34.00 + 34.00 + 34.00) / 4 = 34.00 MPG

Finding the Difference in MPG:

Difference = Average MPG of Good Gas - Average MPG of Go Gas
= 34.00 - 31.00 = 3.00 MPG

Thus, Gabi can drive 3 more miles per gallon if she uses Good Gas instead of Go Gas.
