Answer:
The second deal is better. It is $2.042 per gallon
Explanation:
$11/5 and 51.05/25 are the deals.
Let's multiply the first deal by 5/5.
That is $55 per 25 gallons and the other deal is $51.05 per 25 gallons.
So the second deal is better.
Now lets divide 51.05 by 25 to find out how much dollars per gallon
51.05 / 25 = 2.042, so it is $2.042 per gallon.
