The car travels 27 mile / gallon.

We need to calculate the cost for the car to travel 2727 miles.

First we need to determine how many gallons does the car needs to travel 2727 miles.

We know that:

27 miles ==>  1 gallon

2727 miles ==>  x gallons.

We will cross multiply to find x.

==> 27*x = 1*2727

==> x = 2727/ 27 = 101

Then, the car needs 101 gallons to travel 2727 miles.

Now we know that 1 gallon costs $4.04

Then 101 gallons costs 4.04 * 101 = 408.04

Then the cost for the car to travel 2727 miles is $408.04.
