Answer:

B

Explanation:

We know that Last year one gallon costs $3.00

and we also know that it costs %5 more this year.

We know that %100 is always the same which is $3.00

Then since we know $3.00 is %100, we can add %5 to %100 to get %105.

Then you multiply 105/100 by 3 then you will get 3.15 which is what B is

So that means our answer is B
