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?

Answer 1

Answer: $64.80

Step-by-step explanation:

• 2100 km road trip
• 2 friends + Sathish
• 150 km after begins and 150 km before end
• consume: 6L/100km
• cost: $1.20/L

Friends + Sathish will ride together = 2100 - 150 - 150 =

2100 - 300 = 1800 km

6L/100km = xL/1800km

100x = 6.1800

100x = 10800

x = 108 L

$1.20/L = $y/108L

y = 108*1.20

y = $129.60

Value for 3 people = $129.60

each = 129.6/3 = $43.20

Sathish alone = 300 km

6L/100km = xL/300km

100x = 6.300

100x = 1800

x = 18 L

$1.20/L = $y/18L

y = 18*1.20

y = $21.60

Total for Sathish = $43.20 + $21.60 = $64.80
