The price of gasoline is $3.15 per gallon. The graph shows the pattern t = 3.15g, where t represents the total cost to fill up a gas tank, and g represents the number of gallons of gasoline bought. Which table represents the relationship between g and t shown in the graph?

• Table A: Cost of Gasoline with values of g and t in a certain pattern.

• Table B: Cost of Gasoline with a different set of values for g and t.

• Table C: Cost of Gasoline with values of g and t in a certain pattern.

• Table D: Cost of Gasoline with a different set of values for g and t.

An odometer in a car tells the number of miles a car has been driven. The odometer on Mr. Graham’s new car read 13 miles when he bought it. The relationship between the number of miles Mr. Graham has driven since he bought the car, x, and the number of miles on the odometer, y, is represented by the equation y = x + 13. Which table represents this relationship?

• Table A

• Table B

• Table C

• Table D

• Table E
