it seems simple enough but i can't figure it.
my car gets 20 mpg and an avg. price of 2.49$ gallon
and i need to figure how much it would be for 550 miles.

Two approaches:
550 miles divided by 20 mpg = 27.5 gallons of gas. Multiply by the price per gallon...
Alternatively, combine your ratios: $2.49 per gal / 20 mpg = $0.1245 per mile. Multiply by 550.

Welll, if it's 20 miles per gallon, and each gallon is $2.49, you can assume that your car gets 20 miles on $2.49 in gas. Now, you can solve like this...
(550 miles/1) x ($2.49/20) = $68.48
Hm. I think that's it.

550 miles @ 20 mpg x 2.49/gallon
550/20=27.5 gallons x 2.49= $68.475=68.48

550 divided by 20=27.5 (gallons for trip)
27.5 x $2.49 =$68.475 (money needed for 550 miles)

20 miles cost 2.49
1 mile costs 2.49/20= .12
550 miles cost 550x .12= $ 66

20/2.49 = 550/x
20x = 550(2.49)
20x = 1369.5
x = 68.475
It should cost you approximately $68.48 to take your trip.

d = rate * gallon
550mi = 20 g
gallon = 27.5
1 gallon is $2.49
27.5 x 2.49 = $68.46

550 miles * (1 gal / 20 miles) * ($2.49/gal)= $68.48
