Thread: Help with program homework!!!

I have to write a program that determines the miles per gallon for
3 tanks of gasoline. The program prompts you to enter the number of gallons used and number of miles driven for each of the 3 tankfuls of gas. The program will then calculate and display the miles per gallon obtained for each tankful. I can't figure out how to write the statement to calculate this. Below is what I have. If anyone can help, or give me some idea on where I am wrong, i would appreciate it.

Code:

/* Variable Declarations */
    
    int x, result, miles_per_gallon;
    float gallons_used, miles_driven;

/* Greeting*/

    printf("Welcome to the Acme Mileage Calculator Program\n\n");

    printf ("Enter the number of gallons used:");
    scanf ("%.1f",&gallons_used);

    printf("Enter the number of miles driven:");
    scanf("%.1f",&miles_driven);

    for (x = galons_used / miles_driven;)

    result = x;

    printf("Miles per gallon for this tank is %i\N",x,result);

I know the result is wrong....does anyone have an example similar that uses division?
Thank you.

I am only allowed to use 1 variable and 2 to 3 floats. How do I create the formula only using one variable? I picked x to = the miles per gallon and tried to work backwards...am I way off? Thank you for your help
