You can fill a 15​-gallon tank of gas for ​$38.03 or buy gas for ​$2.50​/gallon.

Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.
A.
The better deal is to fill a 15/ gallon tank for $ 38.03 because the price to fill a 15​-gallon tank of gas for ​$38.03 is ​how much per gallon.
B.
The better deal is to buy gas for $ 2.50/gallon  because the price to fill a 15​-gallon tank of gas for ​$38.03 is how much per gallon.
​(Round to the nearest cent as​ needed.)

Let's first calculate the price per gallon if you fill a 15-gallon tank for $38.03. 

To find the price per gallon, divide the total cost by the number of gallons:

\[
\text{Price per gallon} = \frac{38.03}{15} \approx 2.5353 \, \text{dollars per gallon}
\]

Rounding to the nearest cent, the price per gallon is **$2.54**.

Now, let's compare the two options:
- Filling the 15-gallon tank for $38.03 results in a price of **$2.54 per gallon**.
- Buying gas for $2.50 per gallon is obviously cheaper.

So, the better deal is **to buy gas for $2.50 per gallon**.

The correct choice is:

**B. The better deal is to buy gas for $2.50/gallon because the price to fill a 15-gallon tank of gas for $38.03 is $2.54 per gallon.**
