The correct table is B because it shows the relationship between the number of gallons purchased and the amount spent on gas for each number of gallons with $2.25 for each gallon. This means that the cost will increase proportionally with the number of gallons Jimmy purchases. Therefore, it's important to set up the table with g, the independent variable, in the first column and m, the dependent variable, in the second column.
