(MY WORK)

#include <stdio.h>

int main(void)
{
    int number_of_meals_eaten_at_subway,number_of_meals_eaten_at_Lazy_Moon, sas, salm, eat_this_semester,limit_on_meal_card;

   
    printf ("How much do you spend on a meal atsubway? ");
    scanf ("%d", &sas);
   
    printf ("How much do you spend on a meal at LazyMoon? ");
    scanf ("%d", &salm);
   
    printf ("How many meals will you eat thissemester? ");
    scanf ("%d", &eat_this_semester);
   
    printf ("How much money did your parents put onyour meal card? ");
    scanf ("%d",&limit_on_meal_card);   
   
    number_of_meals_eaten_at_subway =(eat_this_semester - salm*limit_on_meal_card)/(sas - salm);
    number_of_meals_eaten_at_Lazy_Moon =limit_on_meal_card - number_of_meals_eaten_at_subway;
   
    printf ("You will eat %d meals at subway and %dmeals at Lazy Moon ", number_of_meals_eaten_at_subway,
            number_of_meals_eaten_at_Lazy_Moon);
    printf ("You will have %d left on your card",limit_on_meal_card);
   
    getch ();
   
    return 0;
}

sas = spent at subway
salm = spent at Lazy moon

While doing this, I was trying to figure out the math and camealong with this:
Ax + By = C
x + y = D

where we have to solve for x and y. "A" would be spent at subwayand "B" would be spent at Lazy Moon and "C" would be eaten asemester and "D" would be Limit on meal card.

I got:
x = (c - bd)/(a - b)
y = d - b

I do not know if my math is wrong but I can not get what the Sampleis getting which is:
You will eat 76 meals at Subway and 74 meals at Lazy Moon.
You will have $1 left on your card.

Explanation / Answer

please rate - thanks you've got to shorten your variable names. made it muchharder to do #include #include int main(void) {     int number_of_meals_eaten_at_subway,number_of_meals_eaten_at_Lazy_Moon, sas, salm, eat_this_semester,limit_on_meal_card;     int left=0,spent;     printf ("How much do you spend on a meal atsubway? ");     scanf ("%d", &sas);     printf ("How much do you spend on a meal at LazyMoon? ");     scanf ("%d", &salm);     printf ("How many meals will you eat thissemester? ");     scanf ("%d", &eat_this_semester);     printf ("How much money did your parents put onyour meal card? ");     scanf ("%d", &limit_on_meal_card);    for(number_of_meals_eaten_at_subway=1;number_of_meals_eaten_at_subway
