You are going on a road trip over a distance of 300030003000 kilometers with three friends. the car consumes 666 liters of gas per 100100100 kilometers and gas costs \$1.20$1.20dollar sign, 1, point, 20 per liter. if you want to split the cost of gas evenly between the four of you, how much should each of you chip in?

Answer 1

distance = 3000 km
car consumes 6 liters per 100 km.....(3000/100) * 6 = 30 * 6 = 180 liters
180 liters at 1.20 per liter = (180 * 1.20) = $ 216
split between 4 people = 216/4 = $ 54 per person
so each person should chip in $ 54

Answer 2

Each of you should chip in $5.4

Explanation:

You are going on a road trip over a distance of 300 km with three friends.

The car consumes 6 liters of gas per 100 km and gas costs $1.20 per liter.

For 100 km the car consumes 6 liter of fuel, so for 300 km it will consume

`=(6)/(100)* 300\\\\=18\ lit`

For 1 liter of gas it costs $1.20, so for 18 liters it will cost

`=(1.2)/(1)* 18\\\\=\$21.6`

As total 4 persons are there, so each will contribute

`=(21.6)/(4)\\\\=\$5.4`
