Write a program that print the final price of purchase at a store where everything costs exactly one dollar. Ask for the number of items purchased. Compute a sales tax of: • 8 percent if the users purchase is less than $100 • 7.5 percent if the purchase is greater or equal to $100. • //Also if the purchase is over $500, give the customer an additional 10 percent after-tax discount. • Print the purchase price, the amount of tax, the amount of the discount ($0.00 if no discount applies) and the total price. • Output: Enter number of items purchased= 60 the purchase price= 60 $ the amount of tax= 4.8 the total price= 64.8 $

# include <stdio.h>
int main(){
	int a;
  double n,s;
printf("Enter number of items >>");
scanf("%d",&a);
if(a<100)
{
n=(a*8)/100.0;
s=a+n;
}
else if(a>=100){
n=(a*7.5)/100.0;
s=a+n;}

else if(a>=500){

n=(a*7.5)/100.0;
s=a+n;
s=s+((s*10)\100);
}
printf("the purchase price= %d$\n",a);
printf("he amount of tax= %.2f \n",n);
printf("the total price= %.2f$\n",s);
return(0);
