Calculate a discounted price

#include <stdio.h>

int main()
{
  const int level1 = 30;
  const int level2 = 50;
  const double discount1 = 0.10;
  const double discount2 = 0.15;
  const double unit_price = 3.50;

  int q1 = 0;
  int q2 = 0;

  int qty_over_level1 = 0;
  int qty_over_level2 = 0;

  printf("Quantity?: ");
  scanf("%d", &q1);
  q2 = q1;

  qty_over_level2 = q1%level2;
  q1 -= qty_over_level2;
  qty_over_level1 = q1%level1;
  q1 -= qty_over_level1;

  printf("\nThe total price for %d is $%.2lf\n", q2,
    unit_price*(q1+(1.0-discount1)*qty_over_level1+(1.0-discount2)*qty_over_level2));
}
