Answer:

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
