you are getting ready to make a 640- mile car trip. In general, your car can drive 160 miles on 5 gallons of gasoline. How many gallons of gasoline will you see for the trip? You started out with 4 gallons of gasoline in your car and gasoline is $2.29 per gallon. How much money will you spend on gasoline on the trip?

anonymous · Answer

divide 160 by 5=32miles/gallon
divide 640/32=20 gallons
for the next part use this
(20*2.29)-(4*2.29)=$36.64
