Function DrivingCost(float drivenMiles, float milesPerGallon, float dollarsPerGallon) returns float cost

float dollarsPerMile

//calculating dollars per mile

dollarsPerMile=dollarsPerGallon/milesPerGallon

//calculating cost

cost=dollarsPerMile*drivenMiles

Function Main() returns nothing

//declaring variables

float miles_per_gallon

float dollars_per_gallon

//reading input values

miles_per_gallon = Get next input

dollars_per_gallon = Get next input

//displaying cost for 10 miles

Put DrivingCost(10,miles_per_gallon,dollars_per_gallon) to output

//printing a blank space

Put " " to output

//displaying cost for 50 miles

Put DrivingCost(50,miles_per_gallon,dollars_per_gallon) to output

Put " " to output

//displaying cost for 400 miles

Put DrivingCost(400,miles_per_gallon,dollars_per_gallon) to output
