Question

Gasoline costs $3.00 per gallon at a gas station. In the table below, enter the cost for each number of gallons purchased. Then, identify the graph that corresponds to the data in your table.

Number of Gallons Purchased Total Cost

0 ?

6 ?

12 ?

The graph that represents the table data is (enter A, B, C, or D):

Answer 1

I'm not 100 percent sure but but part a is

0 0

6 18

12 36

and then part b is letter A

Explanation:

hope this helps

Answer 2

A.

Explanation:

If gasoline costs $3.00 per gallon, then the complete table would be

Number of Gallons Purchased Total Cost

0 0

6 $18.00

12 $36.00

Now, we have to choose the graph that shows these pairs as points.

Among the options, graph A is the one that shows the linear relation. However, you could see that this graph doesn't show the exact given, but it shows the right ratio of change.

Notice that from the given table, the ratio of change is 3, that is, if you divide 18\6 = 3 and 36\3 = 12. This ratio of change represent the cost per gallon of the gasoline.

So, the graph A shows this ratio of change, because for 2 gallons, there's a cost of $6, and for 4 gallons the cost is $12. Both of them have the same ratio of change 3.

Therefore, the right answer is A.
