How much money will I need for my gas to travel 550 miles

Say Gasoline price is $3.50, and the car is 20 miles / gallon.

550 (miles) x $3.50 = $1925 ?? I guess $192.50 (Not sure).

gas needed = 550/20 gallons = 27.5 gallons
cost = 27.5*$3.5 = $96.25

Given: the price of gasoline=$3.50/g; the car consumes 1 gallon of gasoline per 20 miles, then
550 miles consume 550/20 gallons of gasoline, and
travelling 550 miles needs
$3.5*550/20=$96.25.

550 miles * (1 gallon/ 20 miles) = 27.5 gallons.

27.5*3.50 = $96.25.

550 / 20 = 27.5

27.5 x 3.50 = 96.25
