i have been working on this code

```
'''Calculate the cost of fuel for a road trip'''
def main():
distance = float(raw_input("Enter distance in kilometres: "))
litresPer100K = float(raw_input("Enter economy (ltr/100km): "))
pricePerLitre = float(raw_input("Enter fuel price per litre ($): "))
cost = distance / 100 * litresPer100K * pricePerLitre
print "Fuel cost is $%0.2f" % cost
main()
```

now this works but i need to include how to calculate the cost of fuel for each trip.

i am unsure how to approach this

any suggestion or help would be great

.... dont no how much longer i can look at this :(
