Sathish is going on a 2100 kilometer road trip with 2 friends, whom he will pick up 150 kilometers after he begins the trip and drop off when there are 150 kilometer remaining. The car consumes 666 liters of gas for every 100 kilometers, and gas costs \$1.20dollar sign, 1, point, 20 per liter.
Sathish will pay for all of the gas when he is alone in the car, but he and his friends will split the cost evenly when they are together.
How much will Sathish pay for gas?

Satish will pay $64.8

Step-by-step explanation:

 Kilometres when Satish is alone: 300 kilometres

(150 kilometres in the beginning  and 150 kilometres in the end)

Litres of gas when Satish is alone:  

6 litres of gas per 100 kilometres  

6 x 3 for 300 kilometres = 18 litres

Cost of gas when Satish is alone:  

$1.2 per litre  

18 x 1.2 = $21.6

Kilometres when Satish is with friends: 2100-300 = 1800 km

Litres of gas when Satish is with friends  

6 litres of gas per 100 kilometres  

6 x 18 for 1800 kilometres = 108 litres

Cost of gas when Satish is with friends:  

$1.2 per litre  

108 x 1.2 = $129.6  

Cost for each friend = $129.6/3 = $43.2

Satish will pay: Cost when travelled with friends + Cost when travelled alone  

=$43.2+ $21.6  

=$64.8

So, Satish will pay $64.8
