#include <stdio.h>

int main() {
    double m, n, p;
    double totalAmount;

    printf("Please input the total bill at the vegetable super market (Rs):\n");
    scanf("%lf", &m);

    printf("Please input the total bill at the Buy\'n\'Save shop (Rs):\n");
    scanf("%lf", &n);

    printf("Please input the total bill at the chemists shop (Rs):\n");

    if ( m <= 0 || n <= 0 || p <= 0 ) {
        printf("Error: all values must be positive numbers greater than zero");
        return 0;
    }

    m = m - ( (m / 100) * 10);

    n = n - ( (n / 100) * 12.5);

    p = p - ( (p / 100) * 18);

    printf("\n==========================\n");
