#include <stdio.h>


int main() {
    int quantity;
    double price;
    double total_expense;
    double discount;


    printf("How many items do you want to purchase: ");
    scanf("%d", &quantity);
    printf("Enter a price per item: ");
    scanf("%lf", &price);


    total_expense = quantity * price;
    if (quantity > 1000) {
        discount = 0.1 * total_expense;
        total_expense -= discount;
    }


    printf("The total expense is %.lf\n", total_expense);


    return 0;
