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?

Let us calculate how much gas he will need for the trip. Since he needs 6 liters for 100 miles, he will need x for 4000 miles. Gas is proportional to mileage. Solving for x, x=4000/100 *6=240
In total, this will cost 240*1.5=360$. He has 3 friends, so they are 4 in total. Everyone will have to pay 360/4=90$

Let's calculate how much gas would car consume during the trip.
First, we will calculate how much it consumes per kilometer:

The total consumption for the whole trip would be:

To get the total cost of the gas we multiply the total gas consumed by its cost:

So, each passenger must pay $90.
