(1 gallon)/(20 miles) = (x gallons)/(180 miles)  1/20 = x/180  1*180 = 20x  180 = 20x  20x = 180  x = 180/20  x = 9  It takes 9 gallons of gas to drive 180 miles  (9 gallons)*(3.98 dollars/1 gallon) = 9*3.98 dollars = 35.82  Round to the nearest dollar: 35.82 ---> 36  It costs $36 to travel 180 miles
