You are going on a road trip over a distance of 3000 Kilometers with three friends.The car consumes 6 Liters of gas per 100 Kilometers and gas costs $1.20 per Liter.
If you want to split the cost evenly between the four of you,how much should each of you chip in?
[3,000 / 100] x 6 = 180 - Liters of gas will be used on a 3,000 Km trip.
180 x $1.20 = $216 - total cost of gas over 3,000 Km trip.
$216 / 4 = $54 - share of each one of the 4 people.
