Philip is going on a 400040004000-kilometer road trip with three friends. the car consumes 666 liters of gas per 100100100 kilometers, and gas costs \$1.50$1.50dollar sign, 1, point, 50 per liter.

 If Philip and his friends want to split the cost of gas evenly, how much should they each pay?
the amount of gas it consumes per 100 km = 6 l
the cost per litre = $1.50
the total distance of the trip = 4000 km
If 100 km consumes - 6 l
Then 1 km consumes - 6/100 l/km
therefore amount of gas for the whole trip of 4000 km = 6/100 l/km * 4000 km
the gas consumed = 240 l
cost of 1 l = $1.5
then the cost of gas for the whole ride = 240 l * $ 1.5
  cost = $ 360
there are 4 friends , cost of each friend = $ 360/4 = $ 90
cost each friend has to pay = $ 90
