How much farther will she go if she buys Good gas instead of go gas?
To calculate how much farther she will go if she buys Good gas instead of Go gas, we need to compare the difference in miles driven for each corresponding gallon of gas.
For the first data point:
Go gas: 170.5 miles driven / 5.5 gallons = 31 miles per gallon
Good gas: 127.5 miles driven / 3.75 gallons = 34 miles per gallon
Difference: 34 miles - 31 miles = 3 miles
For the second data point:
Go gas: 316.2 miles driven / 10.2 gallons = 31 miles per gallon
Good gas: 319.6 miles driven / 9.4 gallons = 34 miles per gallon
Difference: 34 miles - 31 miles = 3 miles
For the third data point:
Go gas: 372.0 miles driven / 12.0 gallons = 31 miles per gallon
Good gas: 428.4 miles driven / 12.6 gallons = 34 miles per gallon
Difference: 34 miles - 31 miles = 3 miles
For the fourth data point:
Go gas: 449.5 miles driven / 14.5 gallons = 31 miles per gallon
Good gas: 544.0 miles driven / 16.0 gallons = 34 miles per gallon
Difference: 34 miles - 31 miles = 3 miles
Therefore, she will go 3 miles farther if she buys Good gas instead of Go gas.
