Question

#include <stdio.h>

int main () {
int no_of_kaleidoscopes;
float price, tax, price_with_tax_included, discount, total_price;

/*Number of kaleidoscopes purchased */
scanf("%d", &no_of_kaleidoscopes);

int cost_of_one_kaleidoscope = 5;

price = no_of_kaleidoscopes * cost_of_one_kaleidoscope;

tax = 0.07 * price;

price_with_tax_included = price + tax;

if(no_of_kaleidoscopes <= 1 || no_of_kaleidoscopes == 0) {
discount = 0;
} else if (no_of_kaleidoscopes > 1) {
discount = 0.1 * price_with_tax_included;

}

total_price = price_with_tax_included - discount;

/* Output the total price */
printf("%.2f", total_price);
}
