[Tutor] User input

[URBAN LANDREMAN]

You had a typo with the variable 'gallon_price' and your formula for the 
total cost was incorrect.  Adding float() for the raw_input helps.

This code gets you closer:

mpg = float(raw_input ("Enter your mileage:"))
distance = float(raw_input ("Enter your distance:"))
gallon_price = float(raw_input ("Enter you cost per gallon:"))
make = "Honda"
model = "Accord"

##
print make, model, "mileage is", mpg, "miles per gallon"
print "Total trip cost is US$" , distance * gallon_price/mpg

Others who are more experienced may have suggestions for more elegant code.
